Second season of Hiiro no Kakera.

In Edo in the mid-1800's, fireworks maker Seikichi Tamaya and his friends struggle to live under the harsh morality laws imposed by the strict city councilor, which ban all luxuries, including fireworks. One day, a strange girl stops by Sekichi's shop with an equally strange request: she wants Sekichi to build a firework that can reach the moon.

This is a special to To Heart: Remember My Memories, which includes fighting scenes between all the female characters.
