Tenchi Muyou! in Love 2: Harukanaru Omoi

After another argument among his friends, Tenchi wanders into the woods alone and hears a strange voice from a camellia tree. The moment he approaches, he vanishes. Six months pass without a trace, but Ryoko, Ayeka, Washu, Sasami, Kiyone, and Mihoshi refuse to stop searching.

At last they locate Tenchi's energy, only to find a very different man from the one they lost. He appears older, has no memory of his old life, and is living peacefully with a mysterious woman named Haruna. Reaching him is no longer simply a matter of finding the right place. His friends must break through a world built around forgotten memories before Tenchi chooses a new life from which he may never return.
