I'd like to, uh, recommend Saito Ayada (however the last part's spelled)/Enseimatsu P from NicoVideo for those of you who like cool Osomatsu-san PVs like the following from said user

Their videos are definitely good quality-!

Just... don't sub and/or reupload them. The first video I listed here is stated to not allow reprinting, so considering that and the fact that this nicovideo user's video list is private (so you can only really see their videos from either おそ松さん人力's YouTube video list (who is probably the same person anyway) or searching them up with おそ松さん人力, Saito's P name, and video name, all in JP), Saito probably doesn't want people reuploading their content, regardless on whether or not it's credited and/or subbed.

The second video seems like an intimidating challenge to sub anyway, rEEeE

Edit: yeah it's Saito Ayata (I can tell by their Twitter name). The link to their nicovideo page is also here:  http://sp.nicovideo.jp/user/59168980?cp_in=user_watchInformation
And their Twitter is also restricted to only approved followers, dang. They probably have some sort of bad experience with a thief or something, rip
