A key visual has been released for the second season of The Fruit of Evolution (Shin Shinka no Mi ~Shiranai Uchi ni Kachigumi Jinsei~). It was also revealed that Tomokazu Sugita is joining the cast as Vitor.
The visual features main characters Seiichi Hiiragi and Saria with Destora, Vitor, Genpel, and Yutis.

Shin Shinka no Mi ~Shiranai Uchi ni Kachigumi Jinsei~ will premiere in Japan in January 2023. It is an adaptation of the light novels written by Miku and illustrated by U35. The Fruit of Evolution‘s first season aired during the Fall 2021 anime season.
Hanashi Media describes the light novels as:
One day, Hiragi Seiichi’s entire school is transported to another world. As he wanders through a mysterious forest alone, however, he is ‘attacked’ by a gorilla.
“Me, never sleep with man before. Be gentle.”
All Saria wants is to be close to him. Just when he begins opening his heart to the feminine simian, however, tragedy strikes.
Can the strength of their bond—and the mysterious Fruits of Evolution they’ve both consumed—bring about a miracle?
A lighthearted fantasy-comedy romp through a fantasy world!
