It was really sad. I don't like this when a good mamodo have to leave like that. First Koruru, then Yopopo, now Danny. This is fun to read this manga but when comes to sad things, this is also quite cruel here. I think they could have saved Danny if they just worked fast and take out the book. Then it wouldn't have mattered if Danny was struck by lightening. It was more cruel because they lost Danny even after winning. That's cruel.
