Pulled Trigger - S1.E23

Kyoko's Mio, now progressed, is widely accepted by the entire cast, including Ms. Iizuka. Problems develop, however, when Ren's acting is not up to its usual standard (as predicted by the president in 'Invitation to the Moon') and has to perform numerous takes.

It is later discovered that one reason for the difficulties lies in Kyoko's Mio being somewhat intimidating, though Ren vows to make his version of Katsuki outshine the original and become the equal of Kyoko's character.
