There is a strange rumor surrounding the Urashima Tunnel: it grants the wish of those who enter at the cost of their lifespan. Kaoru Touno did not think much of this silly urban legend until he stumbled across a dark tunnel one night.

Initially dismissing the idea of going in, Kaoru is enticed by the possibility of bringing back his sister, Karen. Karen had died in an accident five years prior as a result of Kaoru's carelessness. As he enters the tunnel, what Kaoru discovers within is not quite the same as the rumors imply. The rules of the tunnel are uncertain, but that does not stop him from testing the waters.

Unbeknownst to Kaoru, his aloof classmate Anzu Hanashiro follows him on one of his expeditions. Much to his reluctance, she is intrigued by the tunnel and wants to team up with him. Although he is wary of her intentions, Kaoru accepts Anzu's offer and spends the summer with her in hopes of reviving his sister.

Preliminary (3/6 eps)
This LN is not recommended! But if u r still going ahead to try it anyway then I hope u hadn't read the synopsis coz if u did.. Then u have almost known the first 30-40% of the story (if not more as I read only 46% of story ig). This might be the case for many LNs, the synopsis might give away the first half of vol 1 but the difference is that this story is only one volume rather than 10+ volumes (for better or worse).

The pacing is completely ruined by big descriptions of nothing important. I wouldn't read another novel by ...
