So from the looks of the OP, they took Itsuki from Rental Magica, half of the female cast from Da Capo and W~Wish (shameless plug?), Ignis from Jingai Makyō, random shit from Persona and did I see Suigintou in there?...for shame. They then threw them together in a situation where I'm assuming the main character, with his all powerful eye, does something so epic, so amazing, that it could only warrant an intense, driving, OP from the creator of such great works like DOLPHIN☆JET and Romancing Story.
