Takes place several years after the events of Boku o Tsutsumu Tsuki no Hikari. Rin and Arisu's daughter Chimako has been born and Ren is nearing adolescence. Arisu and Rin's synchronization with Mokuren and Shion has been stabilized (although they still appear to materialize and hold conversations with each other) but conflicts of the past are not so easily forgotten. Story focuses more on the past like the original. Has more action than the previous series.
