You need Ruputna's skill that can vanish lvl 6 skills though to counter the boss's shinjuu summon skill, which can pretty much end the fight within two turns. I tried using both Ruputna and Thalia together, switching their support roles, and it works but their damage output isn't high enough to prevent the boss from eventually wittling down Nozomu's aura shield and killing him off.

I actually managed it once with Ruputna, Nozomu, and the red cryst but the cryst died at the end and brought my score down. I got really close with Ruputna, Nozomu, and Jaetzia, and I'm gonna try again.



EDIT: Actually it looks like vanishing the boss's start skill seemingly prevents him from summoning his shinjuu later on, and his damage output really went down. This might actually work. o___o

EDIT2: Nope, he still summoned it. X___X But I think I know how to beat him now.

EDIT3: Ding dong the bastard's dead!! And I didn't lose anyone. SS rank plus 20+k mana worth of levelling everyone up. Baahahahaha.
