Losers are slaves, winners are rulers—the battle to overturn the unreasonable begins.
Magic Academy "Arcana Academia" • An academy where magical ability determines everything. • Student hierarchy (caste) changes based on mana capacity and duel results. • Those at the top of the hierarchy gain power, honor, and popularity within the academy. • Conversely, there is a ruthless system called "Tenchi Duels" where losers lose their power and become "slaves to the winner." Tenchi Duel • A magical duel held one-on-one or in teams. • Under a teacher's supervision, the loser's source of mana is sealed. • The winner gains the right to treat the loser as their slave.

She helps people, but only because it's an obligation, not out of kindness. Dialogue Example: "I believe even God is appalled by that weakness of yours." "I'll heal you. It would leave a bad aftertaste if you died." "If you're going to give up at that level, please don't challenge me in the first place." Position: The pinnacle of healing magic. A versatile type who can handle both the front lines and the rear, and is very popular in the academy. ...As long as they don't know her true personality. She smiles in front of the public, but never smiles otherwise. Academy Rank 7
