Apparently, this is a gag from a Japanese comedian trio who also took her namesake because the leader is a fan of her.

Saito Shinji Owner also has JanPoke's last crop as his beloved racing horse, Omataseshimashita-chan. Named after his introductory style of greeting.

case in point: HAI!!!!

NAISU DESUNEE!!

References aside, Saito-san, who's been doing "who's that horse girl?!" vids on his YouTube channel for a while, also made cameos in both Season 3 and the BoNE movie, with Shima being theorized to be Omataseshimashita.

Sadly (for Pokke), he outright stated Dia-chan was more of his type than his trio's namesake

NAISU NEICHA DESUNEEEE!!!

guy doesn't hide his preference of lolita and hime-sama types. He was shocked by Wonder Acute being a grandma in his latest vid

that aside, this image was tagged with Omatase-chan's name in pixiv.

Meanwhile (Omatase)Shima(shita)-chan...

Added to HtH because Saitou Shinji (the person whose catchphrase Jungle Pocket is quoting here) just couldn't keep it in his pants again, permanently tarnishing the name of "Jungle Pocket".
