Tō Endō (遠藤 豆) is Kokonotsu's friend and younger brother of Saya. He also looks out for the cafe and likes to tease his older sister about her love interest.
Similar to his older sister, he has short golden hair that parts to the right. He has brown eyes that are blocked by his signature sunglasses. His wardrobe consists of a Hawaiian shirt and simple trousers.
Not much is known about him besides the fact that he and Kokonotsu used to be classmates back then. Tō also looks out for the café when his sister is not around.
Tō's Question to Kokonotsu at the CaféEdit
One day at Café Endō, Tō asked Kokonotsu why he came to the café. With his response of meeting a girl who is pretty and weird with a love of dagashi, Tō teased him. Tō knew that Kokonotsu is like an open book and he's quite dense around girls especially to Saya.
At the PoolEdit
He joined with Kokonotsu at the pool because the shop's air-conditioner was broken. While they were there, he saw Hotaru in a swimsuit and told to Kokonotsu that he will not attend cram school even though it doesn't actually exist.
Tō has the urge to become popular with girls where he asked Kokonotsu on what makes a guy popular with them. According to his sister's fashion magazine which he borrowed, girls love fortune telling. He then tested it to show that it's true. Tō was amazed by the results and he wanted to know the result if he and Kokonotsu can see a girl's panties. When he used it for the last time, Hotaru saw them since she heard voices and she turned around. At the moment she turned around, Tō and Kokonotsu saw "it" which they didn't mind seeing the final result.
