My Sister Is Off Limits

In a direct confrontation against the people of Artem, Uncle Boo and the Unicorn, Albion, were at a great disadvantage.

Not only did their enemies have great numbers, but all of them were also incredibly strong. Because of this, they never succeeded in their attempt to save Callie from them every time the Lunar Eclipse appeared.

Thirteen had ordered the Wanderers to train how to run, while he asked Uncle Boo to gather all the Sovereigns and all the other Monsters that were Rank 5 and above.

The ten-year-old knew that once the Lunar Eclipse appeared, the majority of the monsters that they had gathered would try to escape so that they wouldn't be killed by the invaders from another world.

He understood that at the end of the day, these monsters would prioritize their own safety over others.

That was fine with him. 

He wouldn't force them to fight.
