I'm pretty sure there is a K-drama with the exact things you mentioned (besides the master) called Rooftop Prince. I don't know if it's a manga as well, but this might surely give you a lead. :)
There were three underlings, a Prince, they were in a fight just before coming to the modern times.
There's a similar anime I've watched. It's The Devil is a Part-Timer.
I just searched it and found a manga.

That’s not it. I am 100% sure it it a Japanese manga.
Thanks though!
Thank you but that’s not it.
I found it! There what it actually was if you were curious: http://www.mangago.zone/read-manga/sengoku_danshi_hana_no_ran/
Looks interesting :) Thanks for this. Will get to it when I have the time :)
So I just remembered a manga I read a long time ago. I think it is shoujo. It is historical, where some guy from the past comes to the modern time. I think he was from the feudal time period. And his master (a guy) come with him too as well as some of his fellow underlings. I remember they were in the middle of a fight where they where teleported. Also I vaguely remember that the guy was against cutting his hair. Please help!
