this anime is one of the best slice of life action-packed comedy I have seen in years. how the writer portraits the different characters and what happened in there life to want to take this dangerous road to bring back there loved one that was lost also that it may be seen as the characters are fighting desperately to revive their friends it also seems like each character has a strong and weak point, as the story progress it leaves us the watchers with many questions that will be answered in the coming episodes
