Raiko wears gloves. It is a fact of the young Iga's lives. Kirara likes to sit as high as she can, Yayoi is the very best at hiding, and Raiko always wears gloves. They are bright red and possibly meant for use in things of a baking nature, but they are Raiko's and she wears them every day.
For all their posturing, the Iga girls are actually very sweet children. It is for this reason that they've banned all Inuzuka and Aburame from ever babysitting them. Raiko insisted after what almost happened to Tsume-san's partner, Kuromaru, and to Shibi-san. She was all of three at the time- still, her mother listened to her reasoning, agreed, and added it to the mission parameters.
All of them are to wear veils until they become Jonin in their own right. Clan law, that.
One of the genin who have to watch them is loud and wears orange goggles. Raiko likes him, but not enough to take off her gloves because it's dangerous Uchiha-san, please leave them alone. He doesn't.
He doesn't die, thankfully, but there's a scar like a handprint on his bicep for the rest of his life.
