Wait, are you seriously asking me to mod this?
I personally do not like StarR's mapping style on this diff very much (It's ONLY my personal preference, I'm not meaning this diff is in low quality/is not well mapped) , but I guess both StarR's Insane & Insane are totally fine to be qualified, if you need my opinion.
About the source, I agree with you. Jubeat is not the actual source of this song.
My only question is whether we do need -takoyaki- as tags? Since your id is the same only with 2 characters capitalized, I doubt we can reach this map using -takoyaki- to search without this tag.
