This whole situation give Ryder more benefits than anything else.

For the fact that human soul have no limit, he have no fear in adding an extra summoning beast.

Visit the devil's plane as a whole is not something common. As a chosen one of the black mark, if he is going to survive, it would be a waste to not enjoy the privilege to the fullest.

This beast in front of him, despite being so small, that fact that it is a devil beast remains. It's strength is on another level.

As he was given the choice to allow this beast into his soul without having an downside, he was more than happy to agree.

As soon as he said yes, Luxy entire body lit up in a deep black aura that distorted the air. Ryder's mark glowed while the rabbit was reduced into thick black smoke that flowed through the air to his shoulder.

Luxy entered into Ryder's body through the mark at the shoulder but that was not where he resides.
