I'll admit it kind of kicks Den-O's intro to the curb, it was almost impossible to take that particular intro seriously.
Compared to Kabuto however, it kind of falls short. Kabuto's intro had the best timing and relative shots to match NEXT-LEVEL. Kiva's looks good so far, but it's kind of unusual in some aspects. looks like the violin aspect is being a little overdone
never seen Hibiki, so no idea
