Lyric

Jigokumon (Hell Gate) is a mysterious portal that appears before VTubers who have already tasted their own personal hell.Those who pass through it don Gothic style uniforms and transform into students of Hell Gate Girls Academy a music project that uncovers new allure through dark, dramatic songs unlike their usual work.

The latest artists to emerge from the gate are two vocalists: Nonchii, whose voice marries sweetness with regal strength, and Shichitenbattoin Aegis, whose beautiful tones have been rigorously trained in opera.

Songwriting and composition are handled by Hainomi, who has been expanding their reach with tracks for artists such as KouShibasaki, Nijisanji talents, asmi, and Nanawo Akari. Planning and production are overseen by nankatanoshii Inc.

The finished track, Wonder Gem, is an empowering anthem that only Nonchii and hichitenbattoin Aegis singers who have both survived their own infernos could deliver.
