Personality & Characteristics


In the original manga, she is a kind but strong-willed young girl who is often the subject of the Matsuno brothers' competing affections.

However, starting in the 1988 anime, she was given a more two-faced personality and selfish attitude, often showing her worse side when things wouldn't go her way.


Totoko is still the love interest of the brothers, and like her 1988 counterpart she is still selfish and wants attention from others.

Starting in Episode 4B: This is Totoko, she becomes a fish idol for her parents' fish shop. This would become a significant part of Totoko's character, as some appearances have her as an idol. In Episode 4B, she not only calls the brothers (besides Choromatsu, who is her manager in the episode), but the townspeople and the press so that she can tell them that since she is becoming an idol, she needs people to buy her unsold tickets for her concert. In Episode 8B: Totoko's Dream, it is revealed that she only wanted to become an idol just so she can become popular, brag to others about her popularity, and have fanboys, which shows her selfish personality. Part of her personality may have been due to the fact, that she was brought up spoiled. However, in "Totoko's Big Panic", she's been going through some character development, learning that things won't always be handed out to her anymore, just because she's cute, and now that she's older. Also in "Totoko's challenge", she participated in an eating contest because as she said in her own words, "I'm not so shallow, that I get lost in my own beauty." Also, one note is that she's trying to stop calling the other people "ugly commoners", (such as in "Totoko's Big Panic") corrected herself and called the other people in the contest, "powerful opponents". Also, she had a rivalry between Nyaa Hashimoto. In which, they won't tolerance one another and get into fight as seen in Episode 33: Jyushimatsu and Dolphin for questioning how many amount of beer, they drank inconsistently at Chibita oden stand.
