"Cellino Joining The Battlefield"

Hearing what Wilhelm said and looking at his tangled face, Joan immediately guessed that Wilhelm still felt the war was too troublesome. 

Well, experts were like this. Don't come to them unless it is urgent. 

It wasn't that urgent yet, so Joan generously nodded at Wilhelm. 

[It's okay. I can do it. But to manipulate so many celestials at once...I need them to gather in one place and make them immobile for a few seconds.] 

Joan knew that the best way to use this puppet master ability was the first time the ability was applied to the battlefield because that's when the effect would be the greatest. 

Once the other celestials realized that there was a puppet master among their enemies, it would be much harder just to 'catch' them as puppets. 

After all, puppet masters also needed close contact with their targets to activate their ability.
