[quote=@Priscilla] The danmaku system is meant to make sure that those five can compete on(relatively) fair grounds with even Cirno, Kingman [/quote] That just adds to my confusion, not lessen it, cause I literally have no idea what they're worried about. In a danmaku battle, Fiona would have to make the Netherworld Express visible to ram people otherwise I (think?) it's a violation of the rules (you need to give your opponent an opportunity to dodge, no matter how slim). Also, when It's supposed to be invisible to normal humans it's basically like how ghosts are invisible to people with literally no power. Marisa is a normal human with magic and she can see ghosts just fine when some random guy off the street in the human village cannot. Also I think it goes without saying using the Netherworld express to terrorize people would PROBABLY construe a massive violation of the danmaku rules and would get Fiona's butt handed to her by those four(five?) if not more.
