After the war against aliens was won and the aliens were completely annihilated (according to the government), there is a lot of clean up needed- space varmints attack people and space vermin are invasive and destroy ecosystems. Instead of continuing school, Sumire works for an extraterrestrial extermination company and sends money to her poor abusive family to protect her brother. When Sumire is abducted by aliens, no one believes her… until the extraterrestrial she was infected with starts taking over her body. The foul-mouthed alien begins as a gigantic powerful arm that has a desire to kill humans. Sumire and the alien fight for control of her body. As the alien takes over more of her, she may be destined to spend the rest of her life as a test subject.
Panels maintain a clean layout with lines focusing on people and action. Fast paced with high energy fight scenes. Yoshiaki embeds humor with the conversations between naive Sumire and the hot headed invasive alien. This action horror blend delves into financial and fear, the pull between good and evil, and corporate control. Many science elements to explore including ecology, pests, species extermination, and symbiosis.
Fab addition for middle school and high school libraries.

I loved this! I love sci-fi manga and this one was so much fun. It reminded me of several other manga I love. I absolute can not wait for the next volumes!

Rai Rai Rai is a funny sci fi action manga that is great for fans of Dorohedoro and Dandadan. Body takeovers, wacky action scenes, and mysterious alien influence all set the tone for this manga. I would recommend this for fans of sci fi shonen manga.
