Sei is smart, has high wisdom, and has a cool head among her generation and her younger generation, as can be shown in the first conflict between Rou and Hobuken. She prefers to avoid pointless fighting and tends to not get into ranks of stronger goblins during non-magic competitions. She may go really far to attain her objectives. She has the habit to spend a lot of money to acquire Grimoires.
As a Hobgoblin Sei wears a traditional hand made mage robe.
Half Spell Lord
Her appearance is like that of a human with two small horns. From her appearance, one could guess that Sei is in the latter half of her early twenties. Rather than calling her cute, she is more like an intellectual cool-type beauty who seems like she would look good in a suit.
Her skin is bluish-white that radiates light green. In the middle of her forehead there is a sapphire-looking round gem 3 cm in diameter (Demon Orb) between a pair of horns. Long, ash grey hair that extends down to her waist. Black tattoos on her forearms with patterns similar to Rou’s yet subtly different.
As a Spell Lord, her appearance almost didn't change from when she was a Half Spell Lord.
