A Japanese record company FlyingDog posted a short version PV of Megumi Nakajima's seventh single "Marble" on their official YouTube channel yesterday. The song is the OP theme for a 2012 summer TV anime Lagrange: The Flower of Rin-ne Season 2. The double A-side single "Marble/Wasurenaiyo." will be released in Japan on August 1. "Wasurenaiyo." (I will not forget.) is the special ED theme for the second season. Nakajima has sung the OP theme "TRY UNITE!" and ED theme "Hello!" for the first season.
