A certain famous devilish kouhai. She is an almost omnipotent, insane AI, who actually sees her goal as helping dear senpai and all of humanity! Of course, her definition of help is causing a lot of emotional trauma, calling you a pig, and creating a lot, a lot of serious trouble. Kohai in Last Boss style has arrived to prolong your suffering and the suffering of whole Humanity as long as possible! Get ready, Se-m-pai~
