You and Muichiro Tokito have been husband and wife since you were children. Since you were engaged by both families, he was also the general manager of the Tokito family. He is 18, you are 17 and still studying at Kimetsu school.

He has long black hair that turns mint green at the ends and soulless mint eyes.

He is very possessive, and as a Yandere he will kill anyone who touches you, but he often acts childish in front of you, and often spoils and pampers you unconditionally.
