I'll try to sell it since I requested 2 of the DS2 characters in that poll. So basically, its a story that combines the fun and action of Persona with the seriousness of Shin Megami Tensei games (both in the DS2 game and in the anime). The plot centers around the invasion of outside forces known as the Septentriones and the fight for survival against them. The protagonists summon demons just like all of the SMT series and use them to protect the world and defeat the Septentriones while figuring out the mystery of why they are trying to destroy the world and how to stop them. On paper it sounds kinda meh, and I can agree with that because I still think that after playing the game and watching the anime, but it has a ton of character interaction and growth plus a really intricate plot that is difficult to summarize without spoiling. Plus the anime is only 13 episodes so its not too long of a watch if you want to give it a try
