Ojisan and Marshmallow

Habahiro Hige is a man in his late thirties who works at a web-related company. He loves Tabekko marshmallows, and his co-worker, Iori Wakabayashi, often teases him about it, by eating them in front of him and buying all of his favourite type from the convenience store. Though her friends do not see what Iori likes about Habahiro, she is actually aiming to be in a romantic relationship with him, and often tries to get his attention, commenting that she likes his marshmallow-like, chubby frame, with Habahiro often unaware of what she is trying to do.

Habahiro Hige (日下 幅広, Hige Habahiro)

Voiced by: Tetsu Inada

A chubby salary man in his late thirties who works in a web related company, he is obsessed with Tabekko marshmallows, to the point that he himself would (at times) hypnotically get drawn in just by the scent of it, which both Iori and MIO5 used to lure and seduce him in order to win his affection. His name "Hige" literally means facial hair which both describes to either "Beard" or Mustache in Japanese

Iori Wakabayashi (若林 伊織, Wakabayashi Iori)

Voiced by: Eri Kitamura

Hige's co-worker, who is in love with him, she often uses Hige's one-track, marshmallow-obsessed mind to win his affection but often finds her efforts stymied.

MIO5 (みおこ, Nijimori Mioko)

Voiced by: Kana Hanazawa

She is a bodacious girl whom Hige accidentally saved from a sex pervert who was groping her while in the train where she later fell head over heels for him. She also works in the same company as Hige as an illustrator. Though she competes with Iori for Hige's affection, she manages to confess her feelings for him, but was turned down because she is already in a relationship with the company president. Despite being thirty years of age, she still passes herself as twenty five in her social media account. She is also an active cosplayer.
