Once Arthur left the cave, he came to learn of the issue regarding Gutcha. After a good night sleep and talking a bit with Lucy, they departed for Earth.
The trip was swift and in a short time, they found themselves in their house. Arthur immediately sat cross-legged and meditated for six straight hours to recuperate Mental Power and return to his peak state.
What he created inside the cave consumed much more than expected but it was worth it, moreover, he only needed less than a day to recover thanks to his Vitality, which broke through one billion points some time ago.
Lucy told him that Gutcha wasn't disguised as a human or else he would have been found by her. Whilst it's true he's proficient at trickery and deceiving people, he cannot escape the eyes of a half-Sovereign who has the power of a God Monarch.
In their group, Arthur is, without a doubt, the best tracker thanks to the countless skills he has and his over-the-top Dexterity.
