The Tunnel to Summer, the Exit of Goodbyes: Ultramarine
Natsu e no Tunnel, Sayonara no Deguchi: Gunjou
Kaoru Tono's heard the urban legend: the Urashima Tunnel doesn't play by normal rules. Find it, walk through, and you'll get whatever you want most on the other side. The catch? You'll age years for it. So when Kaoru randomly stumbles across a tunnel that matches the description, his first instinct is obvious—he thinks of his sister Karen, who died in an accident five years back. Before he can even process what he's doing, the new transfer student Anzu Hanaki shows up, offering to help him test the tunnel out. But she's clearly got her own reasons for being interested, and Kaoru has to wonder: what does she actually want from him? And what's going to be left of him once this is all over?
