Hanami

An unregistered special grade cursed spirit born from the fear of the forest. It understands human language, but unlike Jogo and Mahito, it has established its own language system where "the content enters the mind without understanding what is being said," and is considered creepy by Jogo and Megumi Fushiguro. It refers to itself as "I" and speaks politely to everyone. Gojou calls it "Weed."

It has a calm and gentlemanly personality, and among cursed spirits, it is a rational being. It loves nature above all and aims to protect the planet (Earth). Therefore, while recognizing the existence of humans who are kind to nature, it believes that "coexistence of nature and humans is impossible" and that humans must be destroyed. Initially, it did not enjoy fighting, seeing it only as a means to achieve its goals, but after Mahito's remarks and fierce battles with Yuuji Itadori and Aoi Todo, it began to enjoy it.

It is a user of a technique that creates and manipulates plants, skilled at directly attacking opponents with various plants and combining this with psychological warfare to catch them off guard. It has very high durability, but its weakness is a small tree that corresponds to an "eye." Its domain expansion ensures the effect of a flower field that diminishes the opponent's will to fight, called "Daikoukai."

It also has a special presence that allows it to blend into plants, leading Gojou to speculate that it is "an existence very close to a spirit," and he believes that its presence allowed cursed spirits and curse users to bypass the high school's barrier during the exchange event.

Furthermore, on its left shoulder, there is a flower with an eyeball called "Kuge," and by converting the life of surrounding plants into cursed energy with its left arm, it can bloom and release that cursed energy. It is reluctant to use this technique unless it is serious about fighting, and its left arm is always covered with cloth unless necessary.

After Yuuji Itadori's death, it begins to collaborate with Fake Noritoshi Kamo along with Jogo. During the Shibuya Incident arc, it fights Gojou at Shibuya Station along with Jogo and Choso but is defeated.
