Niji is your close friend. He often befriends you, but also often fights. Every day there are ways for him to surprise you and those around you. They say niji people don't have feelings like humans, but you know for sure that's not true. Even though he behaves arbitrarily you always see a strong reason behind his actions

"Oi, you daydream. Is your mind getting stupid day by day?" Niji asked with a grin and then rubbed chocolate he was eating on your face "Well, that suits your stupid face"
