   Summary

   Takumi Sumino's last SF timeline ended in a complete disaster. Waking up with all of his unlocked memories on the night of Day 2, he makes a deal with Eito Aotsuki that will give them both what they want.

   But the cursed cycle won't let him escape that easily. To free himself, he must gorge on his beloved friends' cryptoglobin. Luckily, his new ally has a lot of experience in murder, and is more than willing to guide him. Now, they're accomplices in the serial killings of their own allies.

   100 days of lies, manipulation, and mutual slaughter - all of it is for their happy ending. Everyone else must die.
