!!Mera!!

full name: Mera Chisato

Birthday: abril 15

Chisato has maroon hair, which she wears tied into two low bunches with colorful beads. She has maroon eyes and wears a pair of round spectacles with a piece of lens missing. Her PE Uniform and swimsuit have other people's names on them since she could not afford to buy new ones. She is described as having a starved appearance.

Chisato is a poverty-stricken, clumsy, very selfish, tactless, self-serving, greedy, albeit determined, remorseful, diligent, mild-mannered, good-hearted girl who frequently breaks dishes and may eat her customer's food. When Kusuo becomes Kuriko for a brief time and has a meal with her, Chisato eats everything. She complains about having to stop eating, Kuriko remarks it is a horrible thing to say. She asks for food from her classmates by giving them an acorn. When she constantly complains about their gifts and steals from them, they are taken away from her and she breaks down in tears and admits to her mistakes. When shipwrecked, she eats everyone's food, but she also gives them safe plants to eat and kills a snake which was threatening their lives. She then apologizes about the food and works really hard to make up for it. She works hard for her family, taking on multiple jobs to support them and possibly skipping meals so her siblings can eat. 20 days after New Year's Day, she states that a bowl of ramen she is having is her first meal of the year and over a summer break she ate mostly grass.Because of this, she will eat anything if given the opportunity, including abusing the free-sample policy, taking handfuls of food samples, and the burnt remains of failed cooking class attempts. Mera is shown to be an air-head on occasion, like when Saiko mails her a laxative bread but she fails to realise that Saiko was the one who mailed it and takes it as a kind offer when it is meant to offend her.

Mera has shown to adapt to eating grass, burned foods and ate a laxative bread without any side-effects. Chisato can survive very well, as was displayed when the group of friends were stranded on the deserted island.

Chisato's family used to be rich but due to a sudden debt crisis, their family sunk into debts and loan sharks took everything and now they are very poor. Because her mother is sick and she has a lot of younger siblings, she has to work more than one job. Not much was exposed about her family but it was said that she has a lot of siblings and is low in financial support. Three siblings can be seen in the anime right before the Okinawa trip, twin brothers and a younger sister, comforting her about not being able to go, before getting a ticket.
