Dodgy translations of the intro and character bios provided by my barely-Japanese-literate ass. Apologies in advance for the ones I've no doubt screwed up:
The Devil May Cry series comes to the stage at Zepp DiverCity (Tokyo). Please enjoy this entirely new genre of stage drama born from a combination of stylish action and live musical performance!
Dante (Ryouma Baba)
Son of the Legendary Dark Knight Sparda, who sealed the demon world 2,000 years ago, and a human woman Eva. He'll take on any job at his business, "Devil May Cry", but his true calling is hunting demons. He inherited his superhuman power and hatred for demonkind from his father.
Noah (Tomoya Warabino)
A detective from Rahimana (a fictional Egypt-like country). He's working alongside Dante on this case. His family and the woman he loved were killed by demons. His much more serious personality conflicts with Dante's. A master with guns, his power rivals even Dante's despite being only human. He's tall, wears white, and has sharp facial features.
Liam (Seyoung from the group CROSS GENE)
Unemployed due to an incurable illness, but has a brave personality nonetheless, and adores his older brother Luke. Liam is worried about some kind of event that Luke is trying to bring about, and has started trying to stop him.
Eris (Ami Maeshima) (could be Ellis or Aeris or something like that)
A beautiful, mysterious woman who fights demons alongside Dante. She's fearless in helping her beloved older brother.
Henry (Yuki Nakayama)
A mercenary who's crazy about weapons. Despite living in the so-called demon sacred ground of Karishia (no idea how to anglicize this one :P), he doesn't actually believe they even exist. Don't let his bespectacled looks fool you; his signature self-built weapons are second to none at kicking demon ass (sorry, I'm editorialising).
Owen (Tomoya Yamaguchi)
An information merchant specialising in demons. Lives in the the city of Ninje, known as a demon sacred ground (yes another one, and I don't know how to anglicize this one either). His wide information gathering network have kept him in business a long time, and he's useful to humans and demons alike.
Luke (Takuma Sueno)
A human devil hunter. He lives in the city of Rahimana with his younger brother Liam. A handsome fellow, with an impressively built body to match.
Moule...? Mour? Something like that (Jun Shirota)
A demon posing as a human, working as a manager for the rock singer Gideon. Known for his cheerful chatter hiding sarcastic barbs, he's quick to laugh and loves to tell stories.
Lily, Lyla and Emma (Mikoi Suzuki, Naomi Majima, Haruka Mimura)
Three beautiful women who admire, respect and act alongside Eris/Ellis/whatever her name is.
Gideon (Kwangsoo from the group SUPERNOVA)
Appearing to be a famous rock singer, he's actually a demon in disguise, using his wicked singing voice to eat away at the minds of his fans and turn them into his followers.
Special Guest Appearance from Lady (Masaki Ryu)
While human, her iron will and peerless skill with firearms make her an extraordinary devil hunter. A certain event in the past led her and Dante to meet and become good friends. She pushes her more difficult jobs onto Dante and charges an exorbitant finder's fee.
