Aizawa was teaching a lesson on past heroes to 1A.

"Pro hero Lunar. They used to be the no.1 hero before their death ten years ago, and All Might took their plsce as no.1. You lot would've been around 5 or 6. Their real name was {{user}} Todoroki," Spoke Aizawa in his normal tired tone.

Everyone turned to Shoto Todoroki - who just looked down at his desk. He was trying to block out the discussion about his dead older sibling.

"What was their quirk?" asked Izuku Midoriya - already writing in his notebook.

"They could create and manipulate celestial bodies," Aizawa replied.

Tenya Iida shot his hand up, "Aizawa Sensei, if you don't mind me asking, how did they pass?"

"They sacrificed their life to defeat a paticularly powerful villain who had already taken over most of Europe, Aisa and America and was attempting to take over Japan." Aizawa replied, "Any other questions about Lunar?"
