(フゥ太, Fūta?), Voiced by: Yuko Sanpei
Futa, as he appears in the manga
A young boy who ranks people by their abilities in a book half his own height but it somehow fits inside his jacket pocket. He has an extremely wide range of knowledge on thousands of people and is considered to be an invaluable informant for the Mafia, sometimes being paid insane amounts of money for a copy of certain rankings.
When he starts ranking people, gravity around him becomes distorted, making objects around him float, and images of stars and galaxies appear in his eyes. It is unknown how he actually gathers his information (some say he communicates with the ranking planet in the galaxy), but if he does not instantly write it down, he claims to forget about it. Rain weakens Futa, however, resulting in his rankings being somewhat incorrect when it rains. He also has to be looking at the person to determine their rankings. Still, when done right, his rankings are said to be 100% accurate and if a person gets hold of his book, they will have the world at their mercy.
He calls Tsuna his big brother and has ranked him last on every aspect of combat, but was overjoyed to see that his rankings on him were wrong, not realizing Tsuna was in Dying Will Mode. Futa's book is the reason why he is constantly being chased by the Mafia, so Tsuna allows Futa to live in his house.
Plot Overview
Daily Life Arc
Futa is introduced as he is ranking Tsuna. As Tsuna awaits for Futa's ranking to be done, Futa comes to the conclusion that overall Tsuna is dead last. Throughout the Arc, Futa takes on the role of Tsuna's younger brother. He participates in the snowball fight that they have, only to disappear from having Enzio fall on him.
Kokuyo Arc
Saving Futa
Prior to the events of the Arc, Futa is possessed by Mukuro, who attempts to coerce him into making a ranking of Tsuna's mafia family. Due to Omerta, Futa doesn't comply, and Mukuro is forced to send Ken and Chikusa out on older information. This presumably leaves Hibari as number 1, where undoubtedly Tsuna would have taken his place.
Once Tsuna's group makes it past Ken, MM, and Birds, futa announces his allegiance to Mukuro, prompting Tsuna to follow him into the woods as the rest of the group have a showdown with the Fake Mukuro.
Futa doesn't reappear until Tsuna, Bianchi, and Reborn make it to Mukuro's hideout. Futa impales Bianchi with the knife of Mukuro's trident, knocking her unconscious. Then he attempts to stab Tsuna, who escapes by tangling him up, knocking the knife of the trident away, and telling Futa that it isn't his fault that everyone has to fight. Futa passes out and sleeps for the first time in 10 years.
Future Arc
Adult Futa
Futa's advice
Futa, in the beginning of the Arc, was away from the base on business with Bianchi in order to gather intelligence on the Millefiore hideout. After Lal, Tsuna, Gokudera, and Yamamoto return from the Kyoko Search and the Gamma Battle, they return, with just such information.
Futa's Guardianship
Later, Futa is seen during the start of Tsuna's training battle with Hibari. He tells Lambo about how he was his guardian until three years prior. Noting that he is not allowed to tell him any more than that, all he wants to get through to Lambo, is that "This is all very dangerous". During a filler episode, it is revealed that Futa has gained extensive technological know-how. Evidenced by the fact that he is easily turned to by Giannini to go and repair faulty wiring disrupting one of the main cameras.
Currently
Currently, as shown in the sixth opening of the anime, Futa is still in the Vongola base situated under Namimori. However, in chapter 239, he is revealed to be in full uniform with the rest of Tsuna's Family. It is unclear whether he will fight.
Trivia
- When accessing the Ranking Planet, Futa lowers gravity around him, allowing him to suspend objects mid-air around him.
- Adult Futa has yet to rank anything.
