The boy who sits next to Yokoi in class, Seki-kun, is always up to
something at his desk. He manages to somehow play very elaborate games
without attracting the teacher's attention. From dominos, to shogi, to
go, to mecha models, to playing with cats and more, he always has
something new to do. Yokoi often finds herself getting reluctantly
interested in his games, even though they always seem to end up getting
HER in trouble with the teacher!
