User blog comment:Inibi Uchiha/Contest your OC as Vocaloid singers!!!!!!!!!/@comment-5904313-20140722193714/@comment-25234327-20140723211110

I have no idea if Neru and Haku are fan-made but since they are both in Vocaloid constantly, at least I see them a lot of times, I suppose Inibi can have them in her contest.
