Miracle☆Train: Oedo-sen e Youkoso

Synopsis

Michi has just attempted to go to a marriage interview meeting only to be declined because she is 14. She ends up on the Miracle Train and explains she hates trains and wants to organize her life because her parents met and fell in love on a train and are disorganized, a life she doesn't appreciate. However, Shinjuku and his three brothers decide to make it the best day of her life by taking her around Shinjuku. She reveals she hates trains because her parents loved them and enjoy traveling, living life without a schedule. Shinjuku shows her a vision of her past where her parents explain that there will be tough and fun journeys that might not go according to plan but as long as there is a way to continue the journey the path will continue forever. She eventually learns to loosen up and grows to appreciate trains.
