Announcement, Song, Opening Animation, and Cover Art

Full Version Released through Mili's Channel

“Not My Paradiso” was first heard through the Hell Maiden opening animation. Mili published the complete song on YouTube on August 2, allowing listeners to hear sections not included in the shorter opening video.

TuneCore lists the digital version for August 3, 2026. Its distribution page is scheduled to display links to individual music services after release, so a direct Spotify URL could not yet be confirmed.

The release retains the official English title Not My Paradiso, with no separate Japanese title listed.

Cassie Wei and Yamato Kasai Handle the Composition

Cassie Wei is credited as both lyricist and vocalist. She composed the song with Yamato Kasai, while Satoshi Yoneda handled the mixing.

Those credits identify it as a Mili production created specifically for Hell Maiden rather than an older song repurposed for the game's promotional campaign.

The title also aligns with the game's premise. Hell Maiden follows Dante after she has already reached Paradiso, only to find herself back in Hell with no memory of her previous life or journey.

Opening Animation Produced by Studio Rosatrium

The Hell Maiden opening animation uses “Not My Paradiso” to accompany Dante, Beatrice, and their renewed journey through the afterlife.

AstralShift confirmed that Studio Rosatrium produced the 2D animation. Its imagery maintains the game's combination of dark fantasy, religious motifs, floral compositions, and anime-inspired character designs.

The opening serves as the visual introduction, while Mili's latest upload presents the complete musical version.

Hell Maiden Continues Dante's Journey

Hell Maiden is an action horde survival deck-building game inspired by the Divine Comedy. Dante mysteriously returns to Hell after reaching Paradiso and must climb toward Heaven again in search of answers.

Players construct decks using Weapon Cards, Mod Cards, abilities, bonuses, and status effects while fighting waves of demons. Dante is accompanied by Virgil, protected by Beatrice, and can rescue Poets of Limbo to unlock additional powers.

The game entered Steam Early Access for PC on July 16, 2026. Its current version includes two Circles of Hell, four Poets of Limbo, four signature weapons, and more than 40 collectible abilities.

Why This Matters

1) The full song expands on the opening animation

The YouTube version gives the composition room to develop beyond the portion heard in Hell Maiden's shorter opening sequence.

2) Its title is directly connected to the game's premise

Paradiso is not merely decorative language. Hell Maiden begins after Dante has reached it and then unexpectedly returned to Hell without her memories.

3) Separate teams shaped the music and animation

Mili produced the song, while Studio Rosatrium translated it into the 2D visual identity of the Hell Maiden opening.

4) The release closely follows Early Access

The complete song arrived shortly after Hell Maiden entered Early Access, making the theme part of the game's initial presentation of its story and world.
