Both are shoujo-ai; Hayate x Blade revolves around swordfighting in an all-girls school; where a determined student who replaces her sister fights on to save an orphanage which is in financial troubles. Hayate x Blade has more comedy and has a pretty upbeat tone surrounding it. However, Shitsurakuen is similar; because I found that they both had the same determination in the atmosphere.
