K-On!, Girls & Panzer Recommendations
Both K-On! and Girls und Panzer soely focus on girls together in a club in high school and have high school slice of life parts as well as their respective main themes of music or tanks. Both practicing and performing in competitions and enjoying life eating out and dealing with life's situations.
In both K-ON! & Girls und Panzer people band together with the hopes of reaching the top. At first reaching the top seems like an impossible task as they are faced with multiple problems along the way, as each of the groups grow at what first seemed an impossible task then starts to seem possible with enough time and effort. As time passes and they continue towards their goal of reaching the top they start to get noticed and more people start supporting them in their journey to the top.
