Rei Kiriyama

Rei Kiriyama is the main protagonist of Chica Umino's manga and anime 3-gatsu no Lion. He is a professional shogi player ranked 5th-dan and a high school student who lives alone in an apartment. Kiriyama initially suffers from depression because of his difficult childhood, where he was orphaned at a young age before being adopted by a professional shogi player. He is also ostracized by his classmates due to his introverted personality, and later by his adoptive siblings after he becomes more skilled than them in shogi. Over the course of the story, Rei begins to progress out of his depression when he makes friends with several people, particularly the Kawamoto family and its three sisters.

r/anime
The 3-gatsu anime, while not garnering much attention as some of the popular series, is positively received in the r/anime subreddit due to its well-developed characters. The second season in particular boasts one of the highest ratings in MyAnimeList, a review aggregator website closely associated with r/anime. Because of this, Kiriyama has established a place as a mid-carder competitor in the subreddit's Best Guy contest, regularly reaching the fourth round since Best Guy 5 and only losing to typical popular candidates. The shogi player pulled off his greatest feat yet in Best Guy 6, upsetting #15 Armin Arlert by just one vote to reach the fifth round - his best finish in the tournament.
