Blackcurrant

"It is I who gives birth to light. At the same time, I am born from light."

Magical Vacation
In order to get their hands on a Dark Veil, the students of Will-o'-Wisp Academy disguise themselves with the Light Veil that was given to them in May Village. Wearing the Light Veil allows them to communicate with the stars scattered throughout Arko, and by making all of them ascend, Blackcurrant reveals itself in the cavern's deepest reaches.

When talked to, Blackcurrant explains how the students are beings of light, while Enigmas are beings of darkness, and that light and darkness will become one in the end. There is no fight against Blackcurrant; instead, he grants the students with a Dark Veil, which lets them pass through Abyssal Corridor as mortals.

Name origin
