Summary
"I need your help. I… I want to move on, but I can’t. Not while I still have unfulfilled desires. And, unfortunately, I don’t think I can do it on my own. Believe me, I’ve tried.”
The boy was looking at him so… earnestly. Takumi had only ever dealt with vengeful ghosts before, but those were more the exception than the rule. It wasn’t unheard of to find ones that were stuck for one reason or another. This could be his chance to learn about peaceful ways of resolving paranormal conflict. “...What would you have me do?”
The ghost looked away shyly. “Ah, well… It’s a little embarrassing to admit, but… I want to be your friend. I’ve never had friends before.”

Summary
Eito finally clears his throat.
“I will admit to you, Takumi… I was planning on offering you up to V’exhness. Anything to see you and your band of abominations crumble.” Eito adjusts his glasses, his gaze stern. “Now, I can’t say whether or not I want to do that anymore.”
Admittely, Takumi is curious. “...is that so…?”
“You still repulse me. But it’s quite the news, after all…”
“Well, what are you going to do now?” Takumi asks.
Eito fixes his glasses and scans the area. “I suppose we should look for shelter for the night.”
“We?!"

Summary
There were many things Darumi regretted. Many things she wished she could've done differently.
The one thing she didn't regret, however, was Takumi."Takumi, I love you." She hoped those words reached him as she was consumed by the flames.
That was the end of it.
Or at least it was supposed to be... so why had she woken up and been sent all the way back to Day 3?

Sirei yes Sirei! (Hundred Line Last Defense Academy SI) by UndeadFrog
Fandoms: The Hundred Line -Last Defense Academy- (Video Game)
24 Sep 2025
Tags
Summary
Being thrown into a new world and then basically dying is unpleasant.
Getting turned into a machine because of your otherworld origins is even less present.
Finding out your new masters are bloodthirsty monsters that want to clense an entire planet in fire, you bet thats not fun.
Learning that your main opponents are all superpowered beings immune to conventional weapons. Probaly one of the worst things ever.
When you figure out the only chance to stop any of this is a group of about 15 children? Well thats just the cherry on the horrible sundae now isn't it?

Summary
It all started when Takumi walked in on Yugamu shirtless (which Takumi will always argue shouldn’t be phrased like that, Yugamu was walking through the halls in the dead of night without a shirt on! Or, bra, really, which isn’t normally something to add when you see a guy shirtless but a lot of things Takumi thought he knew were turned on their head that day).

Summary
“Uh, Hiruko? Did you bite your lip or something? You’re… bleeding.”
Before she can respond, he hears a familiar shout from behind him, and turns to see Hiruko limping closer, clutching her stomach as red drips between her fingers.
It takes him all too long to realize the discrepancy, and where he’d seen that exact shade of starry, ink-black fluid before.
Takumi makes a different decision, and sees a whole new side of the war.
Takes place during the Box Of Blessings route.

Summary
"Yes, I have already told you one non-truth."
"I see..."
He supposed he should have expected as much.
"Any ideas as to what it is?"
Takumi leaned forward, resting his elbows on his knees as he lost himself in thought. Looking back on it, V'ehxness was a remarkably straightforward woman, despite her tendency to avoid voicing her desires.
"Yeah, I've got an idea."
That's what made him so confident in what he was about to do.
An extension of the V'ehxness route. contains spoilers for V'ehxness route, Second Scenario, and SF as well as potential minor spoilers for other routes. Reader discretion is advised.

"Goodbye… Takumi… Fighting with you... It was the only fun I ever had in my whole life."
He would die soon, just a few more seconds and he would be free from the shame, pain and jealousy driving him mad. Yet, the last sound Eito heard froze the blood running through his veins:
The undistinguishable sound of the corpse recovery drone. Oh. Oh no.
(Eito's death gets interrupted. Now he has to deal with the consequences)
