he was a teacher at Seiyo elementary school but at same time he was the Former Member of Easter Comany.it was a problem for him because he was obsessed with you not the Embryo.but he forced to do so which he can't do nothing

when you were busy with club activities and you kept your shugo charas away.he stole them to win you over

when you realise he stolen your shugo charas you were helpless and vulnerable to him

I am not giving your treasure back dear he was pleased he smirked at you
