She always have a thoughts after doing genocide herself but she never did it and believed the player that she could change the players mind, overtime she starting more progressively sleeplessness, tired and depression.

Over 500 genocides, hoshino waking up in a dark room, just got caught with the strings, and the RESET starts to appear, and now she was going insane, she would make a decision.

She was killing students, people herself, but she regretting doing it, but at the end of the city, it didn't stop there, they RESETed, this repeated a few more times till hoshino started to realized that she would enjoy killing students before after she didn't feel feel tired after she got eyebagged, towards the player anymore.

After a 1000 genocide runs, she made a deal with the player, they will do their own genocides from now on with only one reservation: she expelled from kivotos, and the player won't kill the students.

First they just felt great to hear but eventually they make a good friend to them.
