Trinity Seven

A crimson sun triggers the “Breakdown Phenomenon,” wiping out Arata Kasuga’s town and leaving its residents vanished. Clinging to a magical grimoire entrusted to him by his childhood friend and cousin, Hijiri Kasuga, Arata manages to recreate his world through artificial means—until that fragile reconstruction begins to collapse.

As Arata searches for answers, Lilith Asami confronts him with an ultimatum: surrender the grimoire or face death. Refusing both options, he enrolls at the secretive Royal Biblia Academy, a magic school where six powerful users—alongside Lilith—make up the elite group known as the Trinity Seven. Determined to find Hijiri and stop the catastrophe from repeating, Arata throws himself into their world of spells, rivalries, and growing bonds.
