Danger Awaits! Hurry BABEL 2!!

The Children get called away as they are going to school on a mission to save a sunken ship named the Namikazemaru. They use a special submarine named B.A.B.E.L. 2 to teleport into the ship, and find that there were many stowaways among the survivors. Aoi transports all of them back to B.A.B.E.L. 2, but since it has nearly reached its capacity, Aoi transports herself back, which leaves Minamoto with Kaoru while the survivors are unloaded back at B.A.B.E.L. headquarters. Kyōsuke's hypnotism activates once again when he calls Kaoru a kid, much to his shock. Kyōsuke appears before them and informs Minamoto that Kaoru has lost a lot of body heat due to retaining the psychic barrier to keep the ship from imploding. Kyōsuke tries to make Minamoto submit to him, therefore letting him cast a near-permanent form of hypnosis on him, but Minamoto resists long enough for Aoi and Shiho to come back and save them. It is later discovered that Kyōsuke's hypnosis on Minamoto has completely disappeared.
