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? less

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 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... moreRekka finds himself in another complicated situation when four new heroines need his help.

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! less

Rekka is still striving to help Mio, Ellicia, Corona, and Lyun, but things are only getting more complicated. When Mio starts to get her memories back, she reveals an ominous prophecy that really ups the ante on resolving these girls’ stories. The fate of Earth is at stake if Yang gets his way, but Earth isn’t the only place in danger. Can Rekka save both his world and the spirit world at the same time? Or will this be the first time he can’t achieve a happy ending for everyone?

What does Rekka do when an angel literally falls from the sky on him? Go on a date with Iris to a galactic amusement park, of course! It should all be a nice, fun-filled trip, but things are never that simple. Rekka will (unwillingly?) get to try his hand at acting when a desperate director tracks him down. And that’s not to say anything about the kaiju monster that’s lurking just around the corner. Time for a little 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... moreRekka and the girls are going back to school... after a little detour, that is.

Rekka is just starting to think that things have quieted down a bit, and that he might actually get a chance to be a normal high schooler for once. Who knows? He might actually study for his upcoming midterms. One phone call from Hibiki, however, is all it takes to send things spiraling out of control. It turns out Chelsea has a friend who’s come into a very strange problem... moreRekka is just starting to think that things have quieted down a bit, and that he might actually get a chance to be a normal high schooler for once.

It turns out Chelsea has a friend who’s come into a very strange problem. But wait, where did this samurai come from? And how is Atlantis involved? So much for midterms, because Rekka’s about to dive deep on this one! less

It’s fall, which means it’s time for Mitsubashi High’s annual school festival! Things are special this year because it’s being hosted in conjunction with Hibiki’s school, which means extra fun... and extra work. President Momone ropes Rekka into helping with the festival preparations, which turns out to be more than he bargained for when they get sucked into a video game world. Then there’s the bomb threat, the duel, and.. moreIt’s fall, which means it’s time for Mitsubashi High’s annual school festival!

President Momone ropes Rekka into helping with the festival preparations, which turns out to be more than he bargained for when they get sucked into a video game world. Then there’s the bomb threat, the duel, and... Only one thing is for certain—this is going to be a festival to remember! less

Rekka’s now spending his school days kicking it back in lazy style. Class is a bore, but there’s always club activities and the strange, spooky, and sometimes silly errands President Momone has for him. This low-key, peaceful life may be what he’s always wanted, but there’s a peculiar buzzing in the back of his head.... Has everything always been this easy? Or is there something important Rekka is forgetting?

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.

With the mastermind of the extremist faction finally apprehended and the heroines recovered, Rekka and company are about to learn the true nature of the War of All... and there’s a lot more at stake than anyone bargained for. After everything he’s been through, will Rekka be able to cleverly pool his resources one last time and thwart a real apocalypse? Family secrets, divine meddling, time travel, world jumping, and so much more come together for one wild ride in this chaotic finale!
