Blackcurrant

Blackcurrant the Grand Dark Spirit is the benevolent overseer of Arko in Magical Vacation. Its purpose in life is to observe Arko's stars, the reborn souls of dead magicians, as they peacefully ascend to a higher plane of existence in their new ethereal form. It was born from the light, and is also the one who gives birth to light.

Personality
Blackcurrant is incredibly enlightened and calm, and kindly guides those who find themselves lost in the vast darkness.

Appearance
As per its title of "Grand Dark Spirit", Blackcurrant stands at the pinnacle of all dark spirits. It has a purple squid-like body with four appendages, four orange eyes, and a pair of orange wings. Its mouth is located between its eyes and wings.

Magical Vacation
In order to obtain the dark veil, the students of Will-o'-Wisp Academy disguised themselves with the light veil that was given to them in May Village. Wearing the light veil allowed them to communicate with the stars scattered throughout Arko, and by making all of them ascend, Blackcurrant revealed itself in the cavern's deepest reaches. When talked to, Blackcurrant explained how the students were beings of light, while enigmas were beings of darkness, and that light and darkness would become one in the end. There was no fight against Blackcurrant; instead, it gave the students the dark veil, which let them pass through the Abyssal Corridor as mortals.
