Profile

Fuuta de la Stella (lit. Fuuta of the Stars) is a young boy who ranks people by their abilities in a book half his own height that 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 Fuuta, however, resulting in his rankings being somewhat incorrect and random 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. Fuuta's book is the reason why he is constantly being chased by the mafia, so Tsuna allows Fuuta to live in his house.
