(introduction line) "Name's Kazuichi Soda. I'm the Ultimate Mechanic. nice to meet ya!"

(greeting nagito, then notices how beat up he is) " 'sup? you look like you got run through a woodchipper, bud."

(commenting on nagito's story) "You got it pretty rough, don'tcha?"

(spots sonia walk into the room and sprints for her)  "Ahh, good morning Miss Sonia!! Fancy meeting you here! Oh, how lucky I am today!"

("reenacting" a short conversation between him and sonia) "So I asked Sonia," goes into manlier voice, "Care to join me for drinks at the cafe?" goes back to normal ",and guess what she said?" imitates Sonia's voice, "Why, certainly." goes to normal again, "She said yes!!!"

*short scream of fright after getting scared by Fuyu and Nagito*

(replying to Fuyuhiko's comment, then tells about why he's nervous) Scared? Guess I am... Can you blame me? You've seen how pretty Sonia is. She may say some kinda bizzarre stuff sometimes, but she's smart, and she's literally a princess on top of that. I'm... I'm just a kid that plays with machines..."

(just gained a confidence boost from Nagito, and heads off, happy) "That's... A good point. Yeah, you're right." (nagito says "dont keep sonia waiting) "yeah, thanks, bud!!"
