These two animes have a similar setting with a hero with hidden abilities and heroines with tsundere personalities. But Ookami has no magic like Zero, the male main characters are a lot different. Ookami and Louise very similar.

Amagami SS

Both animes have a very melancholy and dramatic (at times) feel to them, while keep the anime upbeat. Both have a similar structure and the main characters are a bit similar. But Yuuichi shows more self-confidence while Junichi is more depressive a times.

Seikimatsu Occult Gakuin
|
These animes are nothing alike in terms of storyline, but in terms of main characters relationship, these two are very similar. Loser and Tsundere (not as much as a tsundere in Occult Academy but close), heading towards the same goal. If you like a slapstick relationship between hero and heroine you should like these two.
