There are different spellings for it. Sempai is one of them.

Nope.

[hider=Actual Facts]I'm currently studying Japanese through my university, but if that isn't enough proof [url=https://en.wikipedia.org/wiki/Senpai_and_k%C5%8Dhai]Wikipedia[/url] and [url=https://www.google.com/search?q=senpai&oq=senpai&aqs=chrome..69i57j0l2j69i59j69i61j0.2020j0j7&sourceid=chrome&es_sm=93&ie=UTF-8#q=sempai]Google[/url] agree with me. A quick search says that out of the three main romanisations of Japanese, all use "senpai". There was one that used to use "sempai" but that was revised to "senpai" over 60 years ago.[/hider]
