Nako Sunao

Nako Sunao is one of the main protagonists of  Hitoribocchi No OO Seikatsu and its 2019 anime adaptation.

She is voiced by Minami Tanaka.

Personality
Nako is a laidback girl who is initially feared by the others for her appearance, particularly that disinterested expression on her face. She also speaks in a rough manner of speaking which furthers the impression that she is a delinquent. She also tends to be blunt with her observations and is generally not bothered by the consequences of her actions.

Nako is somewhat a jokester. She often finds joy in secretly poking Bocchi's shoulders to make her believe that there was someone else with them, or she would poke fun at Aru by calling her "unfortunate" even when she receives a headbutt from her. Aside from this, she truly values her friends and is typically patient when dealing with Bocchi due to understanding her social anxiety.

Biography
Nako is introduced in the first episode of the anime when Bocchi opts to sit behind her during class. After her attempt at introducing herself to the class ended up failing and she vomited, Bocchi decides to fulfill her promise to her childhood friend by befriending Nako. Nako is dismissive of Bocchi at first and questions her about whether she wanted to be her "gofer" in an insensitive manner. Despite coming off as abrasive, Bocchi gives Nako a bottle of honey juice when she started to cough, and she later hands her umbrella over to her when it started to rain (as well as an eraser that she had accidentally dropped during class). Later, Nako became slightly offended by Bocchi after she innocently let it slip that she only became her friend as a means of keeping a promise but later forgives her thanks to the Vice Class President Aru's assistance. Nako also assists Bocchi in befriending Aru, but she often finds herself at odds with her due to her poking fun at her for trying to pretend to be perfect when she was really an unfortunate girl. The two would fight, oftentimes leading to Aru headbutting Nako in anger, but they tend to bury the hatchet whenever Bocchi is concerned.

When Bocchi meets Kai again, Nako is the first one to comfort her when her chance meeting ends badly with her being brought to tears.
