Ciel and her Younger sister, Sistermon Blanc get separated from Gankoomon and Hackmon, finding themselves in Eden. Without knowing how to get back to the Digital World, they decide to set up a training area in Kowloon level three. The two sisters hire Keisuke Amazawa to act as a lackey so that people would attend their training course, as they didn't want to be seen as "too cute and weak" to help train Digimon and Keisuke, whilst wearing a mask to look more intimidating helps them out.

Nokia Shiramine is their first customer of training gym, so Keisuke and the Sistermons fight Agumon and Gabumon and win. After being scolded by Ciel that Nokia doesn't love her Digimon and merely stands in the background supporting them and Keisuke telling her to show her affection to her partners, Nokia responds that they're right and she is why they aren't strong. She then blows kisses to her partners, showing her love for them. Agumon and Gabumon don't seem to understand but say they're feeling happy and fuzzy which results in them digivolving into Greymon and Garurumon. The Sistermons then continue their training, slide evolving into their Awakened forms. They then instruct Keisuke to join Nokia's side and with Keisuke's help Nokia defeats the Awakened Sistermon sisters. Blanc ends up really angry that they lost, whilst Ciel explains that doesn't matter because their goal was to help train their customers, which they managed successfully. Blanc doesn't care though and starts attacking the surrounding area, leading Ciel to sing a lullaby that Gankoomon had taught her to calm down Blanc. When Blanc recognises the lullaby, she stops - only to be punched in the face by Ciel, which puts Blanc to sleep - reverting her to her original form. Ciel explains that her sister's awakened form causes her to love battling a little too much but that the lullaby and a punch to the face calms her down every time, though explains that the lullaby reduces any damage when Keisuke and Nokia show concern about Blanc being punched in the face. Ciel then thanks Keisuke and states she will hire him again in the future.

Upon returning to the Digilab, Keisuke is greeted by the two Sistermon. They explain that after word spread about their successful training centre, they got loads of clients - only for Blanc to completely destroy the arena when her Awakened side lost control again. They then came across Mirei Mikagura who brought them to the Digilab for temporary accommodation until their arena is fixed. They then express happiness upon learning Keisuke that visits the Digilab a lot, so state they will help him out and then any time he speaks to them, they explain the mechanics of raising Digimon, such as what ABI is, or how personalities affect his Digimon.
