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 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!

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?

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!

Rekka has somehow managed to survive that crazy day, and tries to settle down into a new daily life with Satsuki, Iris, and Harissa, but he doesn't even get a moment's chance to catch his breath! Yet again, he's thrown into stories where he has no choice but to rescue the damsel in distress, this time in a village closed off beneath the surface of the Earth!

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.

It’s fall, which means it’s time for Mitsuhashi 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... Only one thing is for certain—this is going to be a festival to remember!

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...?

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 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. 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!Â
