The Tunnel to Summer, the Exit of Goodbyes: Ultramarine

In this 2022–2023 mini-series from Seven Seas Entertainment, writer Mei Hachimoku, alongside translators Alexa Frank and Kim Kindya, adapts the novel into a poignant four-issue manga by artist Koudon. It follows a boy and a girl who discover a mysterious tunnel that grants wishes but exacts a heavy price in time, exploring themes of loss and letting go. This compact, emotionally resonant story matters as a faithful visual translation of a beloved Japanese light novel, capturing its bittersweet atmosphere through Koudon's expressive art.
