 If you liked Seiken Tsukai no World Break |  ...then you might like Rakudai Kishi no Cavalry |
Both animes have male MC that attend martial arts and magic based school. He is surrounded by female characters that love him and were / are his lovers. In World Break MC is totally overpowered just like in Rakudai Kishi. There is a lot of harem situations just like here and tons of bad-ass moments just like here( they are still to come - when the first fight begins :). Also in both animes MC is cool headed and he don't get excited due to some mirror ecchi stuff - he react normaly, usually :D
I watched both shows one after the other some time ago and now I have trouble remembering which was which so yea, they're basically the same show.
