Kanna summary:

Meet Sagaki-san. Your everyday rounin student, whose life got turned around after waking up with Kanna sleeping right beside him. How did this stuttering (and cute!) little girl get there? His problems did not stop there as his boss massacred the entire restaurant he works in.From Baka-Upates:Kagura is a professional slacker with nothing put a part-time job and cram school to keep him company. When a little girl suddenly shows up in his house one day, he thinks things can't get any weirder...until she starts calling him "Daddy"! It's hard enough taking care of an ordinary child, but Kanna -- who doesn't speak his language, isn't from his dimension, and has hordes of evil minions hot on her heel -- is anything but ordinary!
