They start talking more together until they decide to fight, like training, like old times. For that, Sistermon Noir switches to Awaken and a fight begins at the opening of the finals of the tournament.

After the fight against Ogudomon, Hackmon had seen how big the world was and so he decided to go out for a little training, but now he was back. The Sistermon clearly demonstrates the concern they had about Hackmon's sudden disappearance.

In the end, the Sistermon decide to help in the final of a tournament. This was the last Digimon Collectors event. There they found Hackmon, still evolved as BaoHackmon.

As time passes, Gankoomon talks to Sistermon about their help with Hackmon. Gankoomon likes Hackmon, but still maintains his stubborn position in training. Hackmon disappeared.

Gankoomon appears trying to stop Hackmon. Gankoomon explains that this is the "Tower of the Seven Deadly Sins" which contains the power of all seven deadly sins and was used as a pillar for Ogudomon's resurrection.

Tamers were asked to investigate the place. The tower was compared to one of the one of the Seven Deadly Sins, "Gluttony", for devouring its invaders without mercy ... So It was called "Tower of the Seven Deadly Sins".

In the temple it looks like Arkadimon was defeated. Ulforce V-Dramon thanks them for their help. But it seems that other members of the Royal Knights have been absorbed ...

Hackmon and the Sistermon manage to follow the Digimon (Arkadimon, now in Ultimate form) and it looks like Arkadimon went to a temple. Lord Knightmon appears and ask them not to continue following the Digimon, saying that that was Yggdrasil's will.

After training they travel to a snowy region. There they meet with Gankoomon. Apparently there is a problem in the region involving the blizzard and Gankoomon was here to end it. The Sistermon shows to Gankoomon the mysterious Digitama.
