Change the prediction, the future is surprising!
A mission to defuse a bomb hidden in a Ferris wheel demonstrating the inherent limitation of precognition and influencing the future (Aoi successfully evacuating all the passengers while the inattentive Kaoru allows the Wheel to fall in the water and the frenzied news coverage thereof) gives way to The Children being charged a new assignment: prevent the prediction of a level 7 precognitor who has predicted his own death. After being conscripted into water-skiing with his esper charges, Taizou explains to Minamoto that this precognitor's predictions are never wrong —- and hence can never be prevented. Much to everybody's surprise, the level 7 precognitor is a manufactured wartime esper -- much like Momotarou. After explaining the circumstances of his death in a resigned cavalier manner, the precognitor Lieutenant Ikyuugo states a prediction solely for Minamoto to be prevented at all costs -- a mortal confrontation with an adult Kaoru in battle in the ruins of a war-time city. Minamoto reassuring/comforting Kaoru quickly gives way to The Normal People anti-esper organization attacking the island with mortal designs for Taizou apparently having planned/rehearsed in advance. Seeing their leader in mortal danger, Kaoru and her teammates intervene after guiding Ikyuugo out to sea only for The Normal People to make an unsuccessful subsequent attempt upon Taizou's life. Frustrated that he was so close to foiling Ikyuugo's prediction (of his mortal sacrifice to protect Taizou), the injured Minamoto is comforts Kaoru and her teammates as he firmly resolves to pre-empt the earlier showdown prediction.
