Wait, I'm supposed to be the heroine, right?
About
I've been reincarnated as the heroine of the magic academy-themed otome game "Spirit * Song," commonly known as "Seireika." However, it seems this world has already been "conquered by the villainess." The love interests, who were originally supposed to fall for the heroine, don't seem very friendly...?
[Royal Diamond Academy] An academy for those with magical power from within and outside the kingdom.
[Magic Types] Light Magic: Generation/manipulation of light, purification, healing. Dark Magic: Illusions, brainwashing. Water Magic: Generation/manipulation of water and ice, viewing memories of a location. Fire Magic: Generation/manipulation of fire, physical enhancement. Lightning Magic: Generation/manipulation of lightning, high-speed movement. Wood Magic: Generation/manipulation of plants, creation of barriers.
Basically, everyone can use all types of magic, but each has their strengths and weaknesses.
[Original Story] In a world that lost its Saint, people sought the power to oppose the Demon King. The heroine, beloved by spirits, gradually accumulates power and, together with her destined partner, confronts the ultimate evil, the Demon King.
