Sistermon Blanc is a Puppet Digimon whose name and design are derived from "sister" and "Blanc" (Fra: White). It is a girl-shaped Digimon that looks like it's wearing a white rabbit, and is the younger sister of Sistermon Noir. In contrast to its elder sister Noir, it is slightly introverted, and it almost always hides behind its elder sister. It is caring for Huckmon just like its elder sister, and also acts as its escort while accompanying Gankoomon on its journey. Although it is trying to diligently carry out Gankoomon's request and assist in training with Huckmon, it frequently ends up reining in its elder sister's violent manner. A long time ago, in its previous life, it was out on the streets with its elder sister Noir, but they were saved by Gankoomon just as they were going to collapse from exhaustion. In order to repay Gankoomon for saving it and its elder sister, it puts all of its effort into being a chaperone for Huckmon. The triple-pronged "Cross Barbée" lance that it carries as a weapon has both an offensive side and a defensive side.
- Divine Pierce: Pierces the opponent with the Cross Barbée.
- Protect Wave: Generates a protective wave by stabbing the butt end of the Cross Barbée into the ground.
- Cross Barbée
- Grand Sister Cruz (Esp: Grand Sister Cross): Matches its movements with Sistermon Noir and brings down the opponent.

It was charged with Huckmon's care by Gankoomon, and is training Huckmon while accompanying Gankoomon on its journey. However, Sistermon Noir is working half for training, half for fun, and will point its guns and laugh even while admitting that Huckmon is sad. A long time ago, in its previous life, it was out on the streets with its younger sister Blanc, but they were saved by Gankoomon just as they were going to collapse from exhaustion. It carries guns called "Anthony" in its hands.
