Legacy Of The Sky

Prompt by @SilvermistAnimeLoverPrompt 3: Izuku is Shirakumo’s baby half-brother and nobody knows but Inko and their father. Shirakumo’s mother died when he was younger, so he lived with their dad, hence the last name. Izuku’s birth was completely accidental, and unwanted (by their father). However, Oboro loved his baby brother but didn’t tell his friends about Izuku beyond a brief mention once. Of course, in the wake of his death, they’d forgotten that little detail. Izuku grew up with stories of his older brother from his mother, while his father decided to support them out of obligation, but no more. Izuku has the same Quirk as Shirakumo—Cloud. Imagine Shouta, Hizashi, and Nemuri’s shock at seeing this random applicant using a Quirk that once belonged to their best friend. Midoriya has hair similar to Shirakumo's (untamed and wild).
