Ainomori News — On the evening of February 22, 2023, at 8:00 PM, Ainomori welcomed a new member from the underworld — Yoruro made their official debut.
The Arrival of the Underworld’s Demon Lord
Yoruro’s character is set as the demon lord of Mount Danatus in the underworld, wielding the power to control souls. They have embarked on an eternal journey in pursuit of the truth of the living world.
In sharp contrast to Rana’s warm guardian deity image, Yoruro brings mystery, depth, and a captivating presence that makes you want to know more.
The Debut PV — Crafted by Rana’s Own Hands
What made Yoruro’s debut most stunning was their debut PV. The Live2D animation in this video was created by Toba Rana herself.
From character design to motion performance, Rana demonstrated her skill as a professional animator. This is not merely a debut video — it is the finest proof of Ainomori’s technical and creative capabilities, showing that this team has the ability to bring a complete virtual idol to life from scratch.
Mideal’s Day
Yoruro’s debut marks the official launch of Ainomori’s brand-new project, “Mideal’s Day”. This sub-project centers on fantasy, harmony, and love, adding an entirely new chapter to Ainomori’s world.
The forest is no longer only light — with the underworld now part of it, this world has become all the more complete.
“At the boundary between light and dark, truth is waiting.” — Welcome to Mideal’s Day.
