Ok, that's a curious situation, this bank was shared on episode 2, but we don't have the credits for the attack and it looks like a lot Hamano in timing and Ueno for some drawings, both are credited only in episode 1

Timing is pretty similar to the previous henshin by hamano, but drawings can have influence of Ueno, tbh the bank credits for this season is a mess

the effect at 0:27 to 0:40 are also similar from this Ueno scene https://sakugabooru.com/post/show/232521
At least he can be a 2nd KA for this one and the previous henshin cause of these details
