Isekai Cheat Magician (2019)

As we meet a new character she is seen in her bra and underwear.

A female character wears a top that reveals her cleavage,and since her cleavage is revealed in her top when one of the scenes focused on her breast we see her cleavage close up.

A girl says to the male character that he made a promise he would keep her up all night. The scene focuses on her cleavage.

I believe it would be fine if a mature 15 year old watched, however, not a 13 year old because of hormone imbalance.
