第55話: スーパー スーパー スーパー アクセラレーション!! ブラック新幹線カレナイ

55

Hayato and his friends, who are supposed to come to the Ultra Evolution Institute to officially welcome Seiryu as an ally, are forced by Shashot to sit upright for some reason. That's because Shashot didn't get to come on the Tokyo Station sightseeing tour in Episode 53, or participate in the battle in Episode 54. While Shashot is sulking, Seiryu says "leave this to me." Meanwhile, Hayato and the others go to find out why Shashot was only made for the E5. (Source: Shinkalion Wiki)
