A group of Shinkansen fighters held a New Year's party in Hayato's house, and Qinglong, who was temporarily living in Azi's house, was also invited to participate. Qinglong couldn't understand why humans created so many kinds of noodles, and Hayato used the Shinkansen as an analogy to make him understand. The pterosaurs attacked, and the Shinkansen warriors repelled the enemy with the help of Qinglong.
