How could you not expect Yachiyo to be a Buster gorilla if that's what she exactly is in Magia Record? She's only OP for 1 turn, and it's almost a 5 turn of somewhat low damage due to her raw attack being on the lower end of SR Lancers.

Mami is an experience magical girl, but not a veteran. Put this in comparison to Yachiyo who has had 7 years of experience (contracted at 12, now 19), where magical girls are never expected to reach past adulthood in life.

Iroha has the same thing to her 3rd skill, you know.
