What they share
Theysit in Action / Animation / Fantasy territory. If that's the register that drew you to Absolute Whiteness: Magical Girl, the second film will land in a comparable space — through a different lens.
What Trinity Seven: Heaven's Library & Crimson Lord is
A schoolboy inherits a cosmic library and a list of questionable allies. After his cousin abruptly vanishes into interdimensional voids, a demon-teacher offers three ways to patch reality, none of them safe. The real mystery may be whether anyone’s actually reading the terms and conditions.
