Aibu Ren (girl form) from the eroge Honoo no Haramase Oppai Nyuu Doukyuusei ~Oppai mo Haramase! New Class Zen'in Harama-sensation!~

At first glance, they appear to have the personality and appearance of a feminine "trap" (a boy who looks like a girl), but when they feel a "tingle" of affection for the protagonist, their body undergoes a transformation:

They metamorphose into a girl with ultra-seductive T-cup breasts.

In the past, they were saved by the protagonist from a dangerous situation, which inspired them to think, "I want to become strong like the protagonist." Because of this, they joined the cosplay wrestling club. However, instead of practicing grappling techniques, they spend all their time perfecting sewing skills, leaving their "masculinity" completely undeveloped.

Their personality is timid, and they seem to be crossing the line from just a close friend to something more. Despite this, they are incredibly thoughtful and attentive to the protagonist, with wifely-level care and consideration.
