Valkyrie's a massive project and after the dud it was that pirate game, Marvelous simply can't allow itself for another massive delay. I'd expect it to see release early next year, probably along the anime.
Speaking of the anime, profiles for the main characters and a new girl
And the sketch Leanmeanlovemachine mentioned
So wait there's gonna be more than just those three right?
The official website for the Valkyrie Drive -Mermaid- television anime series revealed additional cast members and character designs on Tuesday.
The additional cast includes:
Yuna Yoshino as Akira Hiiragi
Masumi Tazawa as Kasumi Shigure
Asami Seto as Charlotte Shalzen
Hitomi Harada as Momoka Sagara
Mikako Izawa as Mamori Tokonome
Yuka Iguchi as Mirei Shikishima
Yurika Kubo as Meifon Sakura
The "beautiful girl sexy battle action" anime is set on five artificial islands. Mamori is a "mermaid" transferred to one of those islands. When Mamori is attacked, a newly transferred girl named Mirei saves her. The enemy doesn't stop, however, and the two are soon cornered. Just when they think all hope is lost, Mirei kisses Mamori, and Mamori turns into a sword. Mirei then wields the sword and launches a counterattack against their enemies.
The multimedia project also includes Marvelous' "beautiful girl sexy social game" Valkyrie Drive -Siren- and the PlayStation Vita game Valkyrie Drive -Bhikkhuni-. Valkyrie Drive -Siren- will be free to play, but in-game items will be available at an additional cost. In the game's story, female characters run across the mysterious artificial island Siren. The girls utilize their unique abilities and fight against fate to maintain their way of life. Valkyrie Drive -Bhikkhuni- is slated to ship this year.
Hopefully, they're not stuck with a 12 episodes restriction. That's mainly the reason why the SK anime was rushed and became mediocre.
They probably will unfortunately but even if they had 24 episodes I don't think the Senran Kagura anime would've turned out better since they went and altered aspects of the character's backstories and personalities.
