Okay, interesting new character, I like her inclusion, and she's pushing the narrative forward a bit faster...

She's gonna become part of the harem, isn't she?
If you mean "part of the competition for MC", she's halfway to doki doki already. And it also makes it easier to keep using her (since there's clearly been some effort in her creation). So probably, yes.
I have been thinking for a while that this series needs a supportive cast a bit stronger, Tatara's friend and Ranko's group are all in all too weak. But then came the powerhouse, all I can say is WOW.
