COTE: Reincarnated into White Room

[It's Original] After dying, instead of reincarnating into a colourful isekai world with cheats, I reincarnate into the bland, white, White Room. Now, tasked with the mission to expel Ayanokoji Kiyotaka by enrolling in ANHS a year after him, I can finally start making plans to take down White Room. But for achieving that, the most important thing is to defeat Ayanokoji Kiyotaka.
