"Dean Indigo"

The one who came was a young man around Jake's age with a rather quiet and calm temperament, not arrogant or flamboyant like what young people used to be. 

This young man with a calm and quiet aura looked more like the modernized Zev with an opposite character from Zev. 

Zev was playful and had a 'playboy' aura of a gentleman from ancient times but this young man with pure black hair tied into a ponytail was like a calm lake water. 

The young man's pure black hair was actually not really black because it was more like a navy that was so dark that people could only see the navy color under the sunlight. 

The young man was as tall as Jake with a quiet and mysterious temper, just like the guild leader of the summoner guild. 

One would even suspect that this young man with cold amber eyes was the younger brother of that mysterious otherworldly summoned guild leader.
