Sebas

The first intro of the game portrays Senpai as a kind and considerate person. He helps Yandere-chan up off of the ground after bumping into her and is seemingly a friendly person. He doesn't resent Osana for her hostility towards him and simply just follows her orders. He may also be somewhat of a pushover; as he doesn't protest Osana's rude behavior towards him and will accept any love confession that he recieves. This is the reason why Yandere-chan must eliminate her rivals before they confess to Senpai. Second Intro
