Similar Manga to Tora Kiss - A School Odyssey

[Babbitt]

So, I just read the first chapter of "Tora Kiss - A School Odyssey" and am looking for more manga of similar circumstances.
MangaUpdate Page: http://www.mangaupdates.com/series.html?id=77000

What I'm looking for, specifically, is a protagonist that has a very strong power and is either reluctant to use it or lazy like this protagonist. It's a rather cliche type, but I'd like to find some manga that I might have missed with this. I'd also like the protagonist to not be a wimpy character that can't stand up for himself or herself. The protagonist of the above story is lazy but sure of himself, which is my favorite combination (even if cliche). Other things I'd like to see, but can be optional, are as follows:
1. Romance between a childhood friend or other confident female character (an outgoing, forward personality if possible)
2. Attempting to hide power, and is being chased by others to use the power (http://www.mangaupdates.com/series.html?id=72136)
3. Familiar linked to power (like in the story above, which has to do with summoning)

I haven't kept any sort of list for this account; so, list everything you can think of (even if I might have already read it). I'd prefer to avoid shoujo, yaoi, yuri, smut, josei, and hentai.
