BEAST III/R

Beast III/R is an enemy only servant, and you can't get it.
However i think it's an alternate version of Sessyoin Kiara, who is a limited 5 star servant. There will be a few times when you can summon her.

Why are all of your questions so immature? I think most people(including me) won't answer questions that are cringe worthy. Try to ask a normal question without sounding like a degenerate.
