Actually, she is high/top tier in HM's latest patch. She's up there with Mamizou, Kokoro, and Ichirin.
Which tier lists? Is it the western one?
Last one I remember from a Japanese veteran was Kokoro on top, followed closely by a tie between Byakuren and Mamizou. Then Ichirin, below that Marisa, then Futo, Reimu and Nitori.
Though this is just opinion. Miko and Koishi got lower tiers, since not many can utilize them well.
Still, though Marisa wasn't high tiers, her range, dense and fast bullets, and high damage output have always been there as her main points.
I just think that some changes this time in ULiL can use some nerfing.
But Marisa can still butt people with her bottom, which I think most people would agree is what matters.
Her butt is more useful now, compared to her other normals, which is saying a lot.
The discs.
Whoa, whoa. Different silhouette? So the previous one wasn't the last boss?
