How would you write "Turtle-senpai"

Question

Would it be 亀先輩? How would you write "Turtle-Senpai"? 亀せんぱい maybe? I have no idea how to properly add a suffix to a word/name.

Answer 1

If you're asking whether you should write "senpai" as 先輩 or せんぱい, the answer is 先輩. (If you're trying to give off a cute or childish feeling to the text you could use せんぱい, but that's not really something you'd normally do.)

I guess I should mention that you'd never use the 先輩 honorific when referring to yourself, so your handle is rather odd sounding.
