A 4 and a bit rather than 5 because I think a lot of the first act suffers from Magical School Structure Fatigue. That said, inserting someone like Rin into that scenario adds enough interest to stop it being trite. Also, an incredibly well executed Spoiler enemies to Battle Allies fight scene with Rin and Nezha , the Swords Fantasy equivalent of that scene in Robots (2005) where she spins the yellow one round on her back.
