Some Anime Like Kiss x Sis
I am going to recommend you a few good anime that is similar to it. You will probably enjoy the following anime:
Heaven's Lost Property
|This anime is quite similar to Kiss x Sis in the sense that there is two girls fighting over 1 boy. The story revolves around a teenage boy Kouta Oyamada. He is an extremely innocent looking boy. He has recently transferred from Kunpō High School. From here on, the harem story begins. He luckily meets a beautiful girl called Chizuru Minamoto. Now, the next part is pure fantasy. The girl INVITES Kouta to meet her in the music room.(What?!) It turns out that this girl is a fox spirit and she is madly in love with Kouta. I guess it is love at first sight. Chizuru enjoys flirting with Kouta, causing him to be extremely embarrassed and at wits end on what to do.All was going well for the aggressive Chizuru until another girl called Nozomu Ezomori shows up and spoil her fun. It appears that Nozomu is a fox spirit! Just like Chizuru, she is aggressively pursuing Kouta. Now Kouta is the prize. The two girls often fight with each other like you would see in those Jersey Shore girls would in real life. It is very entertaining and funny. There is nothing like 2 girls raising their paws at each other. MEOW!|
