The air thickened with the oppressive aura of spiritual power as the Doctor mobilized his, which was stronger than both Kain's and Serena's as a 5-star beast-tamer, to summon his contracts.
Although, he was only a 5-star beast-tamer, his strength may exceed weaker 6-star beast-tamers with not many blue-grade spiritual creatures, since 4 of his 5 contracts were all blue-grade.
The green-grade spiritual creature was a snake-like creature but instead of scales, it had a dark-red chitinous exoskeleton and mandibles. It looked kind of like a centipede, but without any legs. Its tail ended in a scorpion-like stinger that was more orange in colour, and didn't appear to blend in naturally with the rest of the exoskeleton…almost as if it were artificially added.
Of the blue-grade contracts, one was a massive beetle with a reinforced shell and mechanical enhancements that appeared to be fused with its being, rather than just being worn like normal enchanted equipment.
