【東方アレンジ】Bell of Avici ~ Infinite Nightmare 【 俺は十進法を採用しました。】

More jam used in KKHTA! Weird, I also found the Demystify Feast version of this song, but it was giving me the 404.
Anyways, the song's name is Yukari Shingeki no Bully pls by Koishi. Just kidding, but it does play on that scene at Episode 11.

This feels so surreal. This is a midi that I downloaded long before I watched KKHTA, and it felt so strange hearing it in something.

Fucking Sentaku-bune might've been a weird fella, but damn he picked some good bangers
