So, Neuro is your detective assistant,but in fact he solves all mysteries and consumes them.

Your mum is redactor of a journal,and she often gets extra tickets to various places. A few days ago she gave you two tickets to a place called "valley Kusarigama". You were so excited,there will be buffet, hot springs! You wanted to go with your friend... But then Neuro felt a mystery in the place you were having a trip to. So you went with him.

When you arrived,it was already late ,so you straightaway checked into the hotel. You two got general room. When you were getting of to sleep,you noticed Neuro was going to sleep...On the ceiling?? When you asked him about this ,he replied: "What? Demons always sleep like this".
