Hated by the Opposite Sex (Japanese: 異性を寄せ付けない魔法, Kanji translation: Magic that Keeps the Opposite Sex Away, Romaji: isei wo yosetsukenai mahō)[1] is an unclassified spell, thought to be a black magic curse. This is not the name of the spell, merely its function, the Power Words are unknown.
The spell delivers exactly what is expected: Its target becomes hated by the members of the opposite sex, to the point of inspiring panic and disgust. The curse is somewhat easy to break, using Flow Break is usually sufficient.
