|Fate||Deceased - Dragged by a Truck|
Sakahara had mid-neck length hair with several loose strands sticking out. His slanted eyes could switch from gentle to cold depending on the moment. He is only shown wearing the school uniform.
Sakahara is idolized in school because of his outwardly kind and charming nature, and how he could handle things with no fuss. He was considerate of Ai and was shown to express concern for her and stood up to his friend when he made fun of her. He likes video games. Deep down however, it was revealed that he is actually a jerk with no remorse for his actions, abusively neglecting Kotaro's needs and harming him as a form of stress relief.
Sakahara is AI's handsome senpai who got a lot of attention and would often be found walking by her while she took care of Kotaro, surrounded by friends or classmates. But one day, he defended Ai when he friend began to make fun of her after Kotaro peed on her.
He took off and reappeared later, after Ai discovered the small dogs corpse. He suggested they not speak of it and give Ai some space, expressing concern for her until they noticed everyone else had left. His friends began to mock him for trying to act so worried considering how he talked about the way he treated Kotaro when he was alive. He mockingly critisizes how weak the small dog was, unaware of Ai being nearby as he revealed that he would tie a rope around Kotaro's neck and tie him to his bike, where he would drag him around for miles. He dropped Kotaro off and destroyed the house Ai spent so long to make for him, then took off.
The following day, everyone is horrified to find out Sakahara had been in an accident when his uniform was snagged by a passing truck. He was dragged for miles before anybody noticed or contacted help, and his body had been so horribly mangled that nobody could stand to look at it without feeling sick.
