I watched this anime a long time ago but it is still one of the few animes that gives me a warm fuzzy feeling inside.
This anime tells the story of a high school boy by the name of Kippei and he is a very flirtatious boy who flirts with every female and is know as a player. Well he ends up having to take on a lot more responsibility when his aunt Miyako disappears and leaves her 5 year old daughter Yuzuyu alone. Kippei then is given the task of having to take care of Yuzuyu which along the way causes him to grow up.
This was a really sweet anime that even have some romance in it for you romance junkies like myself. The only downside to this anime is that while it does end pretty well there is also a manga which I definitely recommend that you read as well. The manga gives a much more complete ending and it’s also a little sad too. But one this is definitely for sure is that if you watch Aishiteruze Baby you will be looking for more animes just like it.
