The brand new collaboration between Animation Director Ryousuke Nakamura and Animator Mieko Hosoi, Promise ~sunnyrain memories~, has released new teaser visuals, a trailer, an official website, and an official Twitter account!

It is based on an illustration collection called sunnyrain memories Promise, on which Ryousuke Nakamura and Mieko Hosoi focused when they were in a group of colleagues called ‘Matsukaze Koubou’. The story is a delicate account of the daily life of 4 girls who live on an island. It is written Ryousuke Nakamura with illustrations by Mieko Hosoi. The first volume of the novel, Promise ~sunnyrain memories~, is scheduled to go on sale in early summer 2017 via Ponican BOOKS.

Born on this island,
Always lived on this island
On sunny days and on rainy days
