Buto Suzuki and Haruo Sato are school spirits in Haunted Junction. From time to time, they'll give their aid to solve a problem. However, as Wikipedia says, "They are generally completely incompetent and make the situations they are summoned to help far worse. "
Haru has no fighting ability what so ever and constantly get's into some sort of trouble due to her reckless actions and the fact that she practically carries two little children * I-Pin and Lambo * with her all the time . Multiple times she nearly got Tsuna and the rest of his guardians killed while trying to protect her and contributes nothing except for being a pag-ibig interest and humor to the plot . Kyoko is just as useless as her but at least Kyoko is smart enough to not get in the middle of a fight when she has no fighting ability . Kyoko also is smart enough to argue with the people trying to protect you and to not run away from sinabi people when you are being targeted sa pamamagitan ng multiple assassins .
