"Yeah, by necessity." Senku chuckled lightly. "I was just curious because I wasn't sure if you did speak another language, but I figured you spoke English." Which he did, so he hadn't been wrong. "Which means you usually hear me in English, so I was wondering how different it is." He was smart enough to know he probably had an accent to a native speaker, it only made sense, it was his second language.

"To me, even though I speak English, I always hear you in Japanese. The train's translation defaults to Japanese...Ishigami Village dialect." Senku mused.

For the experience, he switched over to Japanese. "This is how everyone normally sounds to me." He didn't think Roland would understand him. "I also speak Russian, although no one else does that I've noticed."
