Summary
(third person POV with an original female character.)
(all tags may not be used and will be subject to change in the future.)
(I had to remove a lot of tags because it exceeded the limit SO BE WARNED)Nagumo Kazumi, formerly known as ********* ****, is quite the stark contrast compared to her colleagues; with saccharine sweetness and adorable cluelessness that disarms you. If you didn't know any better, you'd assume she was some ditzy university girl, and not a highly trained assassin with a past that could leave your stomach curdling.
Maybe her sanguine demeanor could be attributed to being Nagumo Yoichi's protege and adoptive ward, or maybe it's being used to hide something much deeper, something even she isnt ready to face yet.(I'm really bad at writing summaries.)

Summary
Shin is 15 when Sakamoto leaves, and he’s 17 when he’s invited to a suspicious looking organization.
His life seems to be full of surprises honestly, too much going on and yet not enough, not nearly enough for one person that is. Staring at the singular (somewhat bloody… yikes) envelope in his mailbox and wondering whether or not opening it is a good idea. He sighs and decides to open it because honestly what’s the worst that can happen? Not like he’s got much anyways.

Summary
Even though Master X directly requested Kashima’s presence here, that doesn’t mean he likes it. It’s for the greater good, of course. Somehow, being strapped to some freak’s operating table while they play around with his insides will end up serving the greater good. Master X knows best when it comes to their group’s plans, and yet... Kashima still truly detests this.
And although Kashima hates to think it, having a professional medic on their side may very well be necessary, someday, just in case something happens that requires aid beyond what his own surgical skills can provide.
. . .
Reader takes Kashima apart and messes with his insides (for science!). Kashima (reluctantly) gets attached.

Summary
The boy sighs, scuffs his shoes, swivels around, and says, “Whatever. Gaku, can we all train together?” Boss said to train them enough, which is distinct from fighting and killing. If they’re asking for more then it’s not good enough. He kicks his mace up and points the laser at their feet, watching them scatter before the blast lands. The recoil shoots up his arm like there’s a vein reserved just for that.
Good is when they explode next to the Order. He’s not in charge of the bombs, which sounds like a boring way to die.
Gaku finally finishes his first runthrough, but there's no NG+. Only thing left to do is clean up some past savefiles.
