The B plan takes riders to Usui Pass Railway Heritage Park from Takasaki Station, letting them ride a heritage SL Gunma decked out like the Mugen train from the film, which pairs well with Plan A to give a complete experience.
The A plan takes Demon Slayer: Kimetsu no Yaiba train fans from Ueno Station to Takasaki Station via the Joyful Train, Yamadori.
The older locomotives will be decked out in Demon Slayer: Kimetsu no Yaiba decals, alongside special ekibens (train lunches), goods, and even a Demon Slayer headboard for the train.
