Atelier Resleriana: Apexi Weltex Battle Natural 1star characters only

I love this boss fight. I can't wait to see what other Apexis can do in the future
Resna and Valeria are in their max awaken status since their piece can be obtained naturally while progressing the game.
This is not very hard score battle, this is the score battle where the stats of the boss is similar to the Main story Apexi Weltex
