DIO!!!!!

 

[McAlastair]

@LegionGuy49 Yeah, I saw that too and judging by the year of release and the characters present, I'm guessing that there promoting Touhou Hisoutensoku. Character Titles in order of appearance:

Genso go saikyo no miko (Strongest Gensokyo Shrine Maiden), Hakurei Reimu.

Futsu no Mahōtsukai (Ordinary Magician), Kirisame Marisa.

Kurenai ma-kan no monban - kajinkomusume (Gatekeeper of the Scarlet Devil Mansion - Chinese Girl), Hong Meiling

Chishiki to rekishi no hanjū (Half-beast of knowledge and history), Kamishirasawa Keine-sensei (odd choice since she isn't playable in that game)

Kataude arukado no sen'nin (One-armed, Horned Hermit) Ibaraki Kasen (Wearing Byakuren's dress for some odd reason)

And finally, as played by Papi/Suu,
Atsu kai nayamu kami no hi (Scorching, Troublesome Divine Flame) Utsuho Reiuji
