3-gatsu no Lion

A youth named Kiriyama Rei, who lost his family as a child,

endures loneliness to become a professional shogi player.

Then, through a chance meeting,

he develops a relationship with the three Kawamoto sisters (Akari, Hinata, Momo),

who hail from a working-class district of the city,

and little by little his frozen heart begins to thaw.
