When I first got into the series, I use to think that Kingdom Hearts was action, adventure story about a boy going on an adventure to save the universe but recently I had been rethinking about Kingdom hearts and its themes. I wonder if we can call Kingdom Hearts a tragedy consider the arcs of Sora, Riku, Kairi, Roxas, Xion, Terra, Ventus, Aqua, etc. and they relate to the events of the series? I am not a Humanities/Literature major and my exposure to tragedy in the classic sense is mostly through Euripedes, Sophocles and the Orestes but I wonder if Kingdom Hearts can qualify as a tragedy? I am not expert on either category of tragedy but can anyone who do understand literature, humanities or just plain well read individuals can help me understand the series as a tragedy? I asked this because I read a rumination where the reviewer analyzes the series as tragedy especially 358/2 days and I had never thought that of the series that way.
