Rekka finds out Lea is sleeping in the ocean every night, and suggests she get a job. Lea doesn't know a thing about how the human world works; can Rekka help her?! In addition to his romantic comedy story with Lea, there's also a cute older girl who asks him to join her club, a student council president who wants to catch a ghost, and a date with Hibiki!

Rekka finds himself in another complicated situation when four new heroines need his help. Mio Kotozuka is a beloved pop star who's had a very unusual encounter with a strange fan. Ellicia Otto, an orphan turned thief thanks to a peculiar power she has, is on the run from a powerful group of psychics after learning a dark secret. Zaia Gardendos Corona is an unlucky hero in need of some rescuing herself. And Lyun Sylpheed is a wind spirit who's been driven from her home after a zombie-like epidemic sweeps the land. Rekka, meanwhile, is still just your average high school boy, but he's going to have to figure out a way to save them all!

After everything Rekka and the girls have been through and with summer fast approaching, Iris thinks its time for a beach vacation. And not just any beach vacation, mind you. An intergalactic one that will take them to a bright blue planet of endless oceans and perpetual summer. But the waters--and the secrets--run deep here on Berano. After a group of space pirates shows up to crash their vacation, Rekka will find himself wrapped up in a conspiracy involving the treasure of a mermaid princess.

Rekka is now officially caught up in his grandest, most dangerous story yet— this time it’s his job to help save the future that he screwed up. The first step to doing that, as far as he’s concerned, is rescuing the kidnapped heroines. But that’s going to be a little trickier than imagined, because the heroines in the future aren’t exactly the ones he’s used to. Can he save them all while managing to keep himself in check? The dangers increase by the moment as intrigue looms on the horizon.

Rekka Namidare was a normal boy until his sixteenth birthday. Then a girl suddenly appears from his future, warning him that he'll somehow start an interstellar war! It turns out Rekka hails from a special bloodline that's destined to get caught up in all kinds of trouble. Whenever a story's heroine is in dire need, Rekka will be given one last chance to save her. And in the future, Rekka will have saved so many girls that their jealous love for him will cause the apocalypse!

Rekka and the girls are going back to school... after a little detour, that is. There’s a bit of an accident with Harissa’s magic, and Rekka and Satsuki find themselves on a deserted island. They think they’re all alone, or is that too good to be true? They’d better make it back home one way or another! There’s a new nun in town and Midori’s not feeling well. They’ve also got big plans for a barbeque, but there may be an unexpected guest tagging along too. And let’s not forget about a certain someone lurking in the shadows...

Rekka may think he's learned a valuable lesson about friendship and the people he loves, but putting it into practice wasn't supposed to be the hard part! When Iris, Satsuki, and Harissa all ask him for a date on Sunday, it will put his wits to the test. But if he thinks his worst dilemma is figuring out which girl to spend his weekend with, he's got another thing coming--more heroines! A new transfer student appears to have a mysterious connection to him, but someone--or something--is after her. And a strange phone call from Hibiki...leads to a treasure hunt?

Rekka is still striving to help Mio, Ellicia, Corona, and Lyun, but things are only getting more complicated. When things get serious back on Earth, will he be able to save both his world and the spirit world at the same time?

When a midsummer heatwave rolls in, Rekka invites all of the heroines to the pool. But instead of cooling off, they find themselves in a heated contest for his attention! After that, Rekka's invited to stay at school overnight with the light literature club. It's all fun and games until he ends up getting involved in a supernatural turf war. Things finish off with a festival fireworks show in this summer-packed volume! But what's this about a special mission for R...?
