Inmortal Senpai achieved | Saiko No Sutoka 2.2.8 (Yangire Mode - No Damage)

I finally got it, I'm finally immortal senpai after 4 days of practice, I did, and got some clarification from @BricK Shooter to be able to get this achievement, and that is to avoid using the bunny pages and same with easter eggs Clarification: I made and had a video of how I tried to get the achievement and I succeeded, but the video stopped recording for a moment when I hid in one of the lockers to calm down and also before looking for the last number and also opening the locker where did i get the (fake) key from and so i had to make this video as a recreation of how i got this immortal senpai achievement
