17 years ago, immortals first appeared on the battlefields of Africa. Later, rare, unknown new immortal lifeforms began appearing among humans, and they became known as "Ajin" (demi-humans). Just before summer vacation, a Japanese high school student is instantly killed in a traffic accident on his way home from school. However, he is revived, and a price is placed on his head. Thus begins a boy's life on the run from all of humankind.

Makoto 'Smile' Tsukimoto and his friend Yutaka 'Peco' Hoshino have been playing table tennis together since they were kids, but as they enter high school, they find that the game, and how they see it, has changed. Peco, brimming with confidence and energy, wants to be the best in the world, but the reserved Smile has little fighting spirit and doesn't want to sacrifice others' happiness just to win, despite his innate talent. As the two grow, and experience the ups and downs of the sport – and life – they try to figure out exactly who they really are and what drives them to play.

High schooler Ruri Tanigawa loves shiny things. She loves them so much that she heads into the mountains to search for crystals herself—where she unexpectedly meets Nagi Arato, a graduate student studying mineralogy. As the pair start collecting minerals together, Ruri begins developing a genuine appreciation for science and the beauty of the natural world.
