Sorata Kanda has a real problem - he just can't say no to the cute face of a kitten! However, his lovely strays have finally landed him in trouble, as his dorm doesn't allow keeping pets. Given an ultimatum to get rid of the cats or move out, Sorata makes the mistake of standing up for himself and finds himself exiled to Sakurasou, the home of misfits the school doesn't know what to do with. Yet the more he spends time there, Sorata sees they all have their own incredible talents. None, however, enthralls him more than the latest arrival: Mashiro Shiina, a world class artist who is seemingly incapable of feeding or clothing herself! Since none of the other residents have a shred of responsibility, the onus of 'Mashiro Duty' falls to Sorata; what will become of Sorata and his latest stray, and will he ever achieve his goal of escaping Sakurasou?
Although those 2 series seem quite different at a first glance, both contain an interesting blend of comedy drama and romance; Kokoro Connect being more dramatic whereas Sakurasou more humoristic.
Those shows explore the relationships between a group of students and in spite of an unrealistic setting (supernatural in Kokoro Connect or a bunch of weird people living together in Sakurasou) the way those characters interact with each other and their response to the occurring situations seem quite real.
Both anime have touching emotional moments, if you enjoyed one you may want to try the other.
I really enjoyed both of these anime to start us off. Kokoro Connect is a drama based in a school, similar to Tari Tari. Both include a school club of some sort which both have 3 girls and 2 boys. The main difference is that Kokoro Connect is more about a supernatural matter compared to Tari Tari which is about a normal school club. However I think that they are both really enjoyable and if you liked one you should like the other!
