There are some characters in the OPM verse page for irrelevant characters and that serve no purpose for scaling either.
My proposals for removal are:
Rosie (Who tf is Rosie, this is just a random minor character with like 2 lines of dialogue)
Narcisstoic (Irrelevant character, literally just has Superhuman Physical Characteristics)
Gigakigan (Irrelevant, appeared in a bonus chapter and got killed)
Himiko Natsuno
Daichi Oogami
Genoboyle
These three are allegedly in the same universe as OPM but I haven't seen anything confirm it and their one shots didn't result in serialization, maybe the profiles shouldn't be removed but they shouldn't be in the OPM verse page
Unihorn (Irrelevant and haxless)
170k Year Old Cicada (9-A Demon level that doesn't do anything for the scaling)
