Mini/X/1999

The mini of the manga/anime X/1999 is a mini-sakura tree. They originally appeared at the Official Fanfiction University of X, which has been deleted. The OFU's coordinator, Agent Teena, still owns one in her spin-off.

Despite having the bodies of plants, mini-sakuras are still capable of self-locomotion, and can shake their branches to express laughter.

In Canon
"Sakura" is Japanese for "cherry blossom." A particular sakura tree appears in X, associated with one main character in particular.

Sakurazuka Seishirou was the most famous and talented assassin in Tokyo. He is referred to as the Sakurazukamori, because he buried all his victims under a particular sakura tree, which was nourished by the corpses and remained in bloom no matter the season.
