柳沢 泰造

Seina and Hidetoshi's homeroom teacher, a widower who lost his wife prematurely, continues to embrace his solitary existence.
Taizou, a compassionate and devoted teacher, went the extra mile to assist Seina with her financial woes, presenting her with scholarship opportunities and facilitating her educational pursuits. 

Following unforeseen events, he left his teaching career and currently operates a private tutoring service from his residence.

Regarding intimacy, Taizou has a penchant for slightly unconventional experiences, enjoying light bondage and engaging in **** play.
