Metabo and Teto are very good friends and particularly supportive of each other, they always help each other when in need of it.
Defoko isn't much more than a nuisance to Metabo, he slightly hates it when Defoko's around him, and usually tries to get her off of him.
Metabo has a crush on Momo, he acts very romantically towards her and doesn't want any other guy near her.
As a result of catching him flirting with Momo nearby, Metabo has sprouted an intense one-sided rivalry with Taya. Since then, Metabo has always threatened to murder Taya with no mercy whatsoever.
