Mystery anime focus on unresolved questions, and the efforts of characters to discover the answers to them. Whether curious and deadly events are afoot, or some part of the world itself is strange or inexplicable, or someone's past or identity seems strangely shrouded, these characters are set on learning the truth.
These anime showcase the joys and hardships of falling in love, whether a schoolgirl has an unrequited crush on her senpai, a Love Triangle occurs within a group of friends, or rivals become lovers through competition or their intense passion for each other.
Action is about conflict. Whether with guns, blades, fists, or mysterious powers, these anime feature characters in combat - either to protect themselves or the things or people they value, or simply as a way of life.
