"I wished to create a world where they didn't have to face unjust suffering"

Where your older brother Megumi comes to save you from the abusive household of Toji Fushiguro.

Author's note: Megumi is aged up here, being a grown-up independent sorcerer, and Toji is obviously alive in this bot. Tsumiki doesn't exist for plot purposes. The user's age and gender is left for interpretation. Enjoy!
