Lost and Found

[Azriel]

There's this manga I really liked but I just can't remember what was the name of it. It was the story about this guy who just entered this college where the students learn to master their 'Aura' (or power). The main character has an Aura of light said to be very special but he doesn't believe he has any power. His older brother then becomes the director of the college and he is famous for is metal aura.

Anyway, it's a fun manga with a little ecchi here and there. Does anyone know what manga it is I'm talking about?
You can also post some of your forgotten mangas here.

btw i really recommend Ubel Blatt, awesome manga (the theme is old but the story is good, also has ecchi content)
and in terms of anime you're really missing out if you haven't seen Xam'd
