Dead Dead Demon's Dededede Destruction manga volume 7 features story and art by Inio Asano.

International relations are crumbling as the hotheaded American president demands that the Japanese government share what they know about Invader technology. But the Japanese prime minister has more important things to think about than diplomacy—he wants to make sure his favorite idol is in the bunker with him when the mother ship blows. Meanwhile, the Occult Club is taking a trip to the seashore to meet with someone who claims to have had an extraterrestrial experience! The silly lark ends up revealing something shocking about Oran’s past, but at least the scenery is lovely!
