Yassan

Yassan (やっさん Yassan), also known as the Literary Girl, is a second-year student at Sanada West High. She is well-known for having a crush on Hidenori, and their riverbank encounters are a running gag in the series.

Appearance
Yassan has a slim figure and is of average height. She has black eyes and long dark-violet hair that reaches her waist. She is usually seen wearing the West High uniform, with tall dark socks and sometimes the lavender school sweater.

Personality
Yassan is a romantic with rather fantastical ideals. Her epithet stems from her hobby of writing novels, and she's frequently seen with her bag filled with her works. She's known for having gone to a riverbank to try and experience a boy-meets-girl scenario that she had written down. Upon succeeding in a sense, she tries her hardest to preserve the scenario, even becoming aggressive towards those who threaten to break it down.

Her subsequent infatuation with Hidenori leads her to somewhat extreme forms of behaviour. She chases him on sight (much to his annoyance) and is also a bit paranoid, such as when he sees her walking with another guy who was just a classmate.

Yassan gets embarrassed easily and frequently. When Hidenori glared at her for laughing at him, she took it to heart and was ready to apologize, appearing extremely guilty. She was also almost in tears after knocking him out inadvertently.

She is acquainted with many minor characters, and a description of her in the manga indicates that she's the friendly type.

Additionally, she is one of the less vocal characters in the series, having only a few lines and communicating a lot through facial expressions.

Abilities
Yassan is fairly athletic when she wants to be, being able to match Hidenori (who is himself athletic) for pace and outlast him over distance.
