My Journey of playing Fate: Grand Order

Choking Cu Challain

I choked Cu Challain (Lancer) with all of my XP cards, Lancer Fou Cards, and upgrading his NP using his duplicate.

I am a bad master, am I right?

For those who are curious, he's currently Level 27. Might ascend him later of tomorrow. I need to farm XP cards, especially those 4-stars, again.
