Gen chases Alien Vibe down an alleyway, and police officers corner it. Trapped, it flips around and vanishes. Gen begins to search for it when his knife leaves his belt and stabs one of the officers. Seeing Gen in a position as if he threw the knife, the other officer believes Gen to be the culprit.
Dan manages to get Gen out of custody by taking responsibility for the mixup, but the ultra remains a suspect. Dan suspends him for a week, saying he will take care of the alien. Gen goes fishing with Tooru, Kaoru and Momoko, but they are attacked by Vibe.
MAC arrives and opens fire. Gen attacks and chases the alien, which vanishes. MAC rushes up just in time to see the bar Gen was using against the alien leap out of his hand and kill a construction worker. Believing the visual evidence, the other MAC members surround Dan, but he breaks free from them and runs off after the alien. Dan trips him when he comes out of the tunnel. When Gen says he'll resign so as not to cause MAC trouble and walks away, Dan stops him by throwing his cane. Gen still walks off.
Dan swears to a higherup he will prove Gen's innocence. TBA
