A New Weapon — Part 2
Editors: Sebas Tian, Joker, Speedphoenix

As the figurative furnace cooled, the light surrounding the newly merged item began to dim.

“Wow… “ I blinked, impressed, before reaching towards the final result and grabbing it by the hilt.

The blade glimmered. The light that came from the chandeliers illuminating the room almost seemed to sparkle off its edge. It, the final product, was a blade of Japanese origin—a katana. Specifically, it was a longer sub-type of katana known as a Tachi. Or at least that was what it would have been had its size been any less disproportionate. The blade was so long that drawing it from a scabbard looked like it would be a royal pain. Fortunately, there was no need for me to carry my weapon the same way the average Joe would. I had a magical inventory, and I planned to use it.

My new weapon’s blade wasn’t nearly as wide or thick as the western styled swords that I had been using to date, but its weight matched, no, exceeded its predecessors’ nonetheless. The grip, the part that I had grabbed, was fairly simple as far as its design went. So simple, in fact, that it lacked a guard.

By contrast, its blade was beautiful. It was dyed a fiery shade of crimson and almost seemed to embody the concept of flame itself.

The only thing the weapon lacked now was a name.

And I had just the perfect one in mind.

“Alright, from here on out, your name is gonna be Zaien.” After christening it, I analyzed the weapon to ensure that it had taken on its new moniker.


Zaien: A greatsword in the shape of a katana synthesized by a Demon Lord by the name of Yuki. This blade despises sin and forgives not those that commit it. Through its blade, which only grows sharper and more powerful as it bathes in blood, Zaien convicts sinners of their crimes and delivers their sentences itself. Equipping this weapon leads to a drastic boost in its wielder’s stats. Quality: Immeasurable.


To summarize, Zaien was a crimson blade capable of judging and punishing sinners. And that was precisely why I had given it the name I had. Zaien was a combination of two Japanese words. The former denoted sin, while the latter denoted flame. Together, the two formed a perfect description of exactly what the weapon was.

Its specs were quite literally off the charts. It was obviously not only far superior to anything I’d made to date, but also likely more powerful than anything I would ever make going forward. Yet, according to its description, the sword was still incomplete. I guess that’s probably why it’s got that whole immeasurable quality and all that.

Of course, it went without saying that I didn’t mind. Gradually strengthening a sword that only grew more powerful as it continued to cut was an entire male fantasy in and of itself.

As for the weapon in question? It also seemed quite satisfied with its transformation—which made sense given the sinister air that had possessed it prior. The thick, grudge ladden miasma that it had attempted to channel into me was now replaced with joy. Its happiness was literally seeping into my being. Yeah, I’d say this whole experiment turned out pretty damn well. I see no reason not to use the hell out of you.

“Wow! That thing’s huge!” said Lyuu. “The blade’s got this weird curve to it too. Is it s’pposed to be some sorta cutlass, Master?”
“Nah. It’s a katana.”
“A katana…” muttered Leila. The demon girl was looking at the weapon with eyes full of unbridled curiosity. “I believe they stemmed from the east…”

You know, Leila’s got a pretty serious curious streak, huh? The fact that I’d voiced only to myself was one that I’d only noticed fairly recently.

“I see…” said Lyuu. “Well, uhmm, would you mind lettin’ me see it, Master?”
“Sure. But you might not be able to wield it. It’s pretty heavy.”
“No worries there! I may not look tough, but I’m a warwolf, and strength is somethin’ that just comes to us, y’knowhat the heck!?” The warwolf cut herself off with a screech the moment I handed her the oversized blade. “Why the heck is this thing so heavy!?”

Yeah, that’s pretty much the exact reaction I figured you’d have.

Leila and I laughed as we watched Lyuu, who had already started to sweat in desperation as she did her best not to drop the blade. Only after watching her struggle did I casually take it back.

“Man, you guys sure are mean…” she said as she panted. “I can’t believe y’just stood there n’ laughed even though I was ‘bout to drop it!”
“Don’t blame us. Your reaction was just so classic that we couldn’t help ourselves,” I chuckled. “Anyway, I’mma head out and give ‘er a spin.”
“Do you know when you’ll return, my lord?”
“I’ll definitely be back by dinner, so make sure you make my share!”

I gave the girls one last shout as I walked across the true throne room and left through the front door.


I called for Rir, who had returned to the forest with his underlings, immediately after doing a few practice swings. The reason was obvious. The two of us were to set out to hunt, both to test my new weapon and to earn some much needed DP.

“Wow… Not bad.”

A few minutes after we started, I found myself standing in front of the butchered corpse of the first monster we’d encountered, nodding in appreciation. Needless to say, Zaien had impressed me. The sword had quite literally adjusted its own trajectory in order to better the strike I had executed. As a result, the slash had ended up literally perfect. It had cleanly cleaved the monster into two equal halves. Wielding Zaien just… felt right.

It was in part a result of the way I fought. I had always just relied purely on brute force. I had a lot of power behind my swings, but much of it was wasted. That, however, was no longer the case. The lovely crimson blade assisted me in following through with my attack and thereby put the would-be wasted force to good use. Talk about user-friendly. God damn. And these bonus stats too. Holy crap. My body’s light as a kite. Hell, I feel agile enough to pull off all the crazy acrobatic shit they need stuntmen and wires for in movies. With ease.

The weapon’s auto-assist was a really nice feature, but it wasn’t the only thing that left me feeling pleasantly surprised. Zaien was sharp. Incredibly. Fucking. Sharp. The first swing I used had happened to contain a little bit too much power because of how gung-ho I had been feeling. Thus, Zaien had cut right through both the monster and the tree next to it without the slightest bit of resistance. So sharp was the blade that it scared me. I was worried that I would accidentally end up touching it without meaning to do so one day and end up losing a finger or five.

I suspected that Zaien’s current state at least in part stemmed from the will that resided within it. It had really wanted to be able to fulfill its role as a weapon, after all.

“You’re sharp, you look awesome, and you’re even easy to use. God damn. You’re pretty much the best possible weapon a man could ask for,” I said with a smirk.

Zaien once again began channeling its joy into me in response to the praise I sang it. Huh. That’s a bit of a charming reaction. Hell, I’m even feeling kinda tempted to call it cute.

You know what? I’m definitely going to engrave a fire-based spell into this thing later. Maybe I’ll go with the one I got from one of the books I bought, the one that ignites things it cuts and reduces them to cinders.

Despite eating much more mana, Zaien had, unlike Hasai, spawned with three slots, likely as a result of the ultra high-class materials used in its creation. Wait. Will it be able to do that whole growing by drinking blood thing if it burns things down on contact? Ehh, whatever. I’ll figure that part out afterwards.

I had yet to decide on what I was going to put in the other two slots, but since I didn’t have any ideas off the top of my head, I shelved the thought for another time.

My excitement had been a little more than just obvious. The sheer extent to which it seeped out from my being had actually caused Rir to smile wryly in my direction. But that didn’t discourage me. I continued to spend the rest of the day testing my new blade out regardless.


Editor’s note (Joker): Hey, guys! Joker here. Man, how about that fast update speed, huh? Don’t get used to it though. This was a special occasion, so enjoy it. And now we have Yuki’s main (maybe) weapon, Zaien. Which, if you don’t know, is actually an anagram of Aizen. As in, Sousuke Aizen, from Bleach. No wonder that sword is strong. I guess the Soul Reaper reincarnated into a sword. Wonder how Zaien and Sword-Dad would get along… Hopefully well. All right, time to check the mail box. Let’s see… It seems we got 5 questions from four people, so thank you to Fran Fan (So sorry about you losing your fix. Blame SevenSeas), zekkendo, Tup, and Zehd Cashew for your awesome questions. I do love replying to y’all, so if you have a question for me, leave it down below with the hashtag #AskJoker and I’ll reply to you personally. See y’all in the next chapter, which will probably be out a little longer than this one was.

  1. Oh no… Oh no… Why do I get the feeling that, Zaien will turn into a Intelligent Sword like Master and it’s appearance will be a little girl…

    I seriously hope that it will turn into a Frying pan. Anyway thank you for the update ~

    1. I’m imagining Megumin, if he’s enchanted it (her?) to have that fire spell, since with his mana, it’d be strong enough to cause an EXPLOSION!


    1. I don’t know what Saitou is, honestly. So I can’t answer this fairly. but between Zaien and Sword-Dad, I’d have to say Sword-Dad just due to the amount of tricks he has

      1. saitou is MC name, the sword (or i say A.I in the weapon) if not wrong called Derflinger, as for his personality err some kind like dandy old man type


    1. Going by the flow this novel goes by, it will definitely happen.

      A redhead loli, judging by the appearance of the blade.


    1. Sword and board (Sword and Shield for those who don’t know). I dunno, I just like the thought of having a sword and shield, being the tank and meat shield.


  2. Thanks for the chap~

    The weapon’s LIT MAN!!!
    I wonder if it has some sort of sinner detector ability/skill where it could cut only sinners. So if Yuki (maybe) bumped into some kind of suspect from a certain accident and this suspect said he’s innocent, Yuki could just judge him by cutting his neck or fingers using Zaien after he said “See here, my weapon has a skill to detect sinners, so if you’re not guilty, your neck wouldn’t fly alright, so calm down and letm me cut your neck”
    But well, because everyone commit sin at least once albeit it’s small, it’s still sin so I think this wouldn’t work out?


  3. Thanks for the chapter!


    I’ve been wondering this for a while but when and why did the term “from now on” changed into “going forward”? I can’t remember when i last saw the “from now on”. Not that i have any complaints on it, just a little curious. In all honesty when i read “going forward” i always remember the movie Meet the robinsons or sometimes i think of its literal meaning in my mind instead (lol) before i remember this means “from now on” then i always end up laughing to myself XD.

    Ps. I’m not saying to change it or anything, just wanted to know why westerners use it now.


    1. Maybe it would be selectable; the gravity of the sin?
      Also: not blocking jokerks response slot.
      Do not take my reply as a response.
      Just reply to this person.


  4. Call me a stickler for the details but when it comes to melee weapon enchantments, especially against lifeforms that use electricity to transmit signals through their nervous system, I personally think Electricity is the best enchantment for the job.
    Fire seems like an obvious choice but a heat based flame requires time to inflict damage to the target, and it risks destroying the delicate temper. Heat needing time to burn is why you can wave your fingers through a flame and not burn yourself. That is unless the flame lingers like napalm but that is another thing.
    Electricity can act like a taser. With the quick slash, you can lock up the muscles of the target and cause them to flinch for a moment and that can be lethal in close combat.


  5. Aizen? 😀

    btw, the sword have 3 slot? wow that’s a lot, what will he put in there? if it’s me i will put Card oppss Magic 😀 a Sealing Magic that will Prevent him using any kind of Magic and Skill or it can be said it Sealing their Mana and prevent them to use it. for the 2nd Slot i will put another sealing magic that will Prevent them from Healing&Recover by himself and recover by getting healed from other, so any Cut will them get permanent Bleeding from the wounds. for the 3rd Slot i will put a Magic that will let him Sword Cut their Spirit and Soul.:D

    Thx for the chapter ^^


  6. After reading a lot of fluffness, the editor note really does help lessen the diabetus disease that has occurred along the way! Too bad the story itself was treated like a side dish for my taste.

    Black kat-sama, i missed you… am not demanding anything, just stating my feeling outloud. Tee hee.


  7. 3 slots which is more than normal weapons?
    Neverwinter’s artifact weapons also have 3 enchantment Slots



  8. Second time reading through. You know, when I read this chapter the fist time Aizen was the furthest thing from my mind. I was thinking of another overly long katana held by a guy who may or may not have been a demon. The jury’s still out on what his mom was.
