d2b VS DEARDROPS -Cross the Future-

A celebratory fandisk for OVERDRIVE's 5th anniversary, crossing over Kira☆Kira and DEARDROPS. Riho watches Kirari and Shouichi's overseas concert on TV, noticing Shouichi seems more into it than before. She wonders if she could beat Kirari. Little does she know, that thought might just become reality. From Micchi's blog.
