This looks to be a double cute unit!!!
Jpopmusic’s ampedechoz posted the above image which states that the mysterious group Kira*Pika is a unit whose members include Morning Musume’s Kusumi Koharu and C-ute’s Hagiwara Mai. The song has tie-ins to the anime Kirarin*Revolution although the nature of those ties are yet to be explained. The unit’s first single “Hana wa Puun/Futari wa NS” will be released on August 1st.
