I feel like Souda and Kirigiri's friendship originally started through Hinata.
Like, Hinata introduced them to each other because Souda was like "BUT SOUL FRIEND I NEED TO MEET HER AND SEE IF SHE'S WORTH IT"
And then he's all casual like "Well I guess we're friends now because you're Soul Friend's girlfriend. I'm going to use your first name and everything."
And Kirigiri just really doesn't mind.
