Okto

Okto is a younger sister of Ilia, and the Eighth chapter of the Ilias Fragment. She appears in the prologue of Inferno World & Fragments Girl cleansing herself, before predicting Tres' arrival within Dante's Gate.

Personality
She seems to be a cautious and timid girl.

Appearance
She appears to be a smaller version of Tres, wearing a white robe. Her hair is tied in such a way that it seems as if she has a pair of horns on the sides of her head.

Dante's Gate
She was first introduced as Arata and co. were entering Dante's Gate. She conjured an army of undead to attack the intruders. She terminated the attacks as soon as Arata sliced off the head of the undead general, and became a guide to the party within Dante's Gate after that. Also, she explained the situation of the other chapters of the Ilias Fragment as well as their originator to Tres due to her not being present with them during that time period. After getting separated, she was left with Akio to deal with Melacoda.

Abilities
Due to her lack of support within Dante's Gate, her capabilities are not confirmed, other than being capable of summoning an army of undead soldiers.
