This thrilling sci-fi/fantasy series welcomes you to Japan, a top-ten destination for extraterrestrials looking for refuge, relaxation, a good time, or just to raise a little hell!

Join one unsuspecting Tokyoite as he discovers that intergalactic tourist relations can prove to be a lot more dangerous than they seem!


Akira Gunji, Sho Tenkubashi, and Raika Nadeshiko plunge headfirst into a cosmic clash against Raika’s doppelganger Ririka—an assault weapon wreaking havoc across the stars! The odds seem insurmountable until Kaito Toya, Raika’s unexpected ally, rockets onto the scene, catapulting Akira and his crew into an even more daunting battle.

Then, apart from saving the universe, Akira faces a quintessentially mundane challenge—he flunked a high school test! His schoolmates Sho and Masato Kizaki assemble at Akira’s house for a tutoring session. Little do they realize that Masato’s stay on Earth is more than just academic—it’s a mission to find a bride!

Oh my gosh the cliffhanger!!! I cannot wait for volume 8! This is gonna be a wild ride.

I love that we got some more "regular life" chapters in this volume. It's fun to see how the A.M.O function on the day-to-day. The side characters are so well done too. They're unique and realistic!

CO, DO CHOLERY, STAŁO SIĘ TE DZIEWIĘĆ LAT TEMU?!

Amamiya jest jaki jest – potrafi być uroczy i sympatyczny (aczkolwiek również wredny i nie przegapi okazji, aby komuś dogryźć), ale gdy trzeba staje się zimny i wyrachowany, zamieniając się w prawdziwego potwora. Wrogom nie okazuje żadnej litości, nawet gdy się poddają.
No właśnie – wrogom. Dlaczego więc z zimną krwią zabił ojca Gunji’ego…? Czy to, że w tym tomie wspomniano o pasożytniczej odmianie obcych ma z tym jakiś związek? I co z tym wszystkim ma wspólnego matka Akiry? I kim ona w ogóle była?!
TYLE PYTAŃ!

A zamiast odpowiedzi dostajemy uroczego Natsukiego.
Natsuki przez przypadek spotyka przyjaciółkę z dzieciństwa i odżywają w nim dawne uczucia. Poza tym, że staje się obiektem żartów Reiji’ego, który teraz to mu żyć nie daje, Natsuki na chwilę spuszcza z tonu i porzuca sztywną i profesjonalną maskę… no, może nie na rzecz rumienienia się, ale faktycznie pojawia się w nim coś ciepłego, gdy myśli o Chizu. Tylko czy będzie im dane nacieszyć się sobą?
Niestety wzmianka o pasożytniczych obcych nie pojawiła się na darmo…

Kizaki on the cover! Good!

Somehow this manga make me feels like it's really serious and not serious at the same time. To be honest, I don't know how to feel about that.

And so much happening in this volume.
Chapter 29: damn, the battle looks nice. And Toya make it more good.
Chapter 30: oh? That's how the ending of this battle? Somehow kinda let down.
Oh not really, I guess? That one aliens is same race with Tenkubashi, nice.
Chapter 31: oh my, the coincidence -_-
Chapter 32: why we suddenly following this guy, oh nevermind, to meet the new character I guess.
Chapter 33: I see big dillema is coming~~

Altro bel volume, scorrevole, divertente e stavolta anche con una punta di romanticismo, tra una battaglia e l'altra contro gli alieni. Si chiude la saga che vede coinvolte Ririka e Laika, un epilogo che tutto sommato ci sta. Dopo un capitolo di transizione, ha inizio un nuovo arco narrativo che coinvolge da vicino il nostro bellissimo Hyogo. Si prospetta molto interessante, ma intravedo già la tragedia materializzarsi davanti ai nostri occhi, spero proprio di sbagliarmi.

I want to like this series more. The artwork is great and the paneling and pace are well done. The story is just too jumpy and somehow repetitive at the same time. The last chapter or two of this book are almost from some other story entirely and seem to add little to what is happening. So much potential, but not enough in the end.

kinda disappointed we didn't get any development with the very clear parallels between sho and raika/ririka cause that seemed like a golden opportunity but maybe they'll come later on?? i'm enjoying how tight the ensemble seems to be so far so i really hope we continue to focus on these characters and not go too crazy with introducing new ones like lots of other shonen tend to do

I enjoyed the slice of life chapters we got in this volume. I hope they are not setting up my man Natsuki for some heartbreak. Hopefully, I don't have to wait too long for the next volume.
