Love In Another Dimension

Umiko Takeda is a 15 year old who's friends and family is basically nonexistent. Her mother- a successful neurosurgeon- is almost never home, her father- a cargo ship captain- is constantly drunk or away, and her 3 older siblings just don't care enough to acknowledge her existence. Her only comfort is anime, specifically My Hero Academia. Every year on her birthday, she leaves home to celebrate by herself, returning in the early hours of the morning. But things have changed this year, and Umiko doesn't return home. Instead of sneaking back home before dawn, she wakes up and finds herself in a familiar dorm in an all to familiar place.
