Hasmodai

Of all the children (even Palza and Mel), appears to be the most emotional and weak-willed, with Hiisuma perhaps being the most cold-hearted and strongest. Enma nearly consumes him twice, tempting him with memories of the life he could have had on earth, where he had been born into a noble family. He and Tarlant also express their desire to have a little bit of fun every now and then, which leads to them taking Wanda out on something of a joy ride and consequently being punched in the face by Agi.
