Harem anime with a strong male protagonist like...?

I just finished watching Isekai no Seikishi Monogatari and loved it.

What I am looking for is an anime with the same feel, not the same setting or same plot but the same basic feel.

For example animes I consider to be like Isekai no Seikishi and why.

Tenchi Muyo! - Harem, comedy and the male lead is strong (somewhat form the get go but when get finds out how to use the light hawk wings its on)

Zero no Tsukaima - Harem, comedy and the male lead is strong ( not so much at the start but as he comes to realize his powers he and his partner become the strongest set of people in the whole setting)

Princes Lover - Harem, comedy, strong male lead ( Although hes strength isnt the focus of the show they elude to it during different parts of the show. )

Goshuushou-sama Ninomiya-kun - Harem, comedy, strong male lead ( Shows you from the get go as he kicks a bears *** with his fists and feet )

Chrome Shelled Regios - Strong male lead, light comedy and not really a harem although he does have a few girls around him and a few that like him its pretty evident that he cares for someone from the start and doesnt stray from that. Also He is so strong that the show is pretty much about pointing it out.

Along with those above I have also seen Hayate the Combat Butler, They are my noble masters and Ichiban Ushiro no Daimaou.

I know its a tall order and not a very common type of anime but if you know any shows that were not listed that have the same kinda of guide line please let me know.

Quick guideline sum up: Harem, Strong male lead ( Sorry no Love Hina type leads ). Comedy, Ecchi, Romance, Action are all +'s to the first two but are not deal breakers if not present.

Thank you for taking the time to read and reply.
