Template:Rain Weapons Chikusa Kakimoto uses one or two Hedgehog Yo-Yos as his choice weapons. The yo-yos are red, butterfly-shaped, and have long strings for ranged attacks and small holes on their sides. They were first used in Chikusa's battle with Gokudera.
The holes in the yo-yos are capable of shooting needles and the strings also seem to be harmful, as Chikusa was able to slice Gokudera's dynamite sticks with them. Moreover, the speed the yo-yos move towards or even change direction is extremely high. The needles inside of the yo-yos number in the millions until a point where Chikusa has a "Needle Shower" attack, from which the name "Hedgehog Yo-Yo" is taken. In the future, Chikusa is also able to cover the needles in Rain Flames.
