Dandadan #12

Okarun suddenly wakes up and finds himself in Hokkaido in a ghost-like form. There, he informs Seiko about the danger of the alien invasion. Turbo Granny teaches him a secret to win the battle and how to return to his body, which he sets out to do. Meanwhile, Momo and the others prepare for the next alien attack by training to improve their coordination. Then, when they return to the city on the day they expect the attack, the aliens are already there! While the others fight, Momo and the Serpian head to the portal to prevent the bulk of the enemy forces from reaching Earth!
