Aquaplus has a crossover of their own for Tears to Tiara II. Early copies include a code that adds Aruru from Utawarerumono as a playable character. Aruru rides Mukkuru, a baby tiger she raised, just like in the anime series. That’s fair since other Tears to Tiara II characters ride elephants.
Tears to Tiara II comes out on October 24 for PlayStation 3.
