My theory of death

Shiho Todoroki was Shotos twin but was abandoned with Touya at the age of 6 and Touya at the age 14.

Her dreams were to become a hero but life choose a different path for her.

Will she be able to accomplish her dreams at the end?
And what kind of end will it be?

I apologize for any spelling mistakes. English is not my first language and this is my first time writing. Some things might be cringe or badly written, but oh well I have to start somewhere.The story won't be exactly same as the anime and some things will be excluded and changed.

All characters except Shiho Todoroki belong to Kohei Horikoshi.
