I thought she would be Arts or something, but that's OK, I guess. She becomes come close to "4-stars Karna" or something like that.

She increases Iroha's Buster performance, but she is Arts, though Iroha did have 2 buster cards, so, she can roll with it as well. And Iroha also gives 30% NP to Yachiyo.

I see, so you're shipping Iroha and Yachiyo as well...//Kiara's Smile//
