Kiro (Japanese: 黄色, Kīro, Eng. Translated: Yellow, Korean: 키로) is a minor character in Tenkai Knights. She is also Chooki's younger cousin.

She is voiced by Laura Bailey.

Appearance
Kiro is a 5-year-old girl with blonde hair and green eyes. She wears her hair in pigtails and wears a pale yellow dress. She is also always seen holding her stuffed dog named Sandy.

In the Series
Kiro was one the main characters in "Fortress Revealed", where Chooki asked the boys to babysit her since he had to go to a soccer game. She had fun with Guren, Toxsa, and especially Ceylan, until the point where her doll became affected by Brickification and then cried. When she saw Ceylan fixing the doll, she took his core brick and locked herself in the bathroom. It took Ceylan giving her a speech about values on objects for her to get out of the bathroom and give the core brick back. After when the boys came back from Quarton, she thanked Ceylan for fixing her doll and invited him and the others to have fun.

Chooki
Chooki is Kiro's cousin. In "fortress revealed" Kiro has to be brought over to Guren's house by Chooki to babysit her. He left her with Guren, Ceylan and Toxsa while he has to go to his soccer game. While Guren, Ceylan and Toxsa were looking for Kiro in Guren's house for Ceylan's core brick, Chooki is back from his soccer game and knew that Kiro was hiding in the bathroom. While Guren and Toxsa are fighting at Quarton, Chooki stay by until Ceylan gets his core brick back.

Guren
Guren, as well as Ceylan and Toxsa, has to babysit Kiro for the first time while Chooki was at his soccer game. In "Heart turns to stone", Guren is the only one who has to babysit Kiro, much to Guren's annoyance. He decided to take her to the park and then ran into Beni.

Beni
Beni met Kiro when she was running down the hill and then bumped into her. She then ask Beni, as well as Guren to play with her but Beni refuses, causing Kiro to yell so much until she will play with her. Beni then plays with her but she didn't enjoyed it. While Guren ask Beni to watch Kiro while he get drinks. After Beni ruined Kiro's sandcastle and walked away, Kiro went missing, but eventually Beni found her and Kiro gave her a four-leaf clover to make her feel better as well as Kiro wanting to be Beni's best friend. Later on, Beni decided to play with Kiro again and gave her the Tenkai Stone to give to Guren the next time she sees him.
