Such a tough decision. So many different types of themes. I'll go with Natusme Yuujinchou. This 日本动漫 is my all time 最喜爱的 for a reason (story, characters, animation, and MUSIC). All the 音乐 is so amazing, all the opening and ending songs. But the 音乐 that is woven within is so beautiful and brings back the memories. <3 The hard 问题 is, which song to post from this series.
