314: Miracle born of blood [pt1]
"Mother! Mother, we have a big problem. Do you remember the nest of blood butterflies we found and tried to destroy? It is blooming right now. We have no idea what happened and we cannot get close enough to figure it out as well."
Sean looked pale and tired when he made it to Amane and the trio. His eyes showed genuine fear and even Amane agreed that it was an emergency.
Blood butterflies were one of the deadliest creatures in the world and they were also the reason behind all the 'vampire' rumors.
As the name suggested, the blood butterfly was a beast that survived on the blood of other creatures and it was a completely black butterfly that looked like a swallowtail butterfly. It was impossible to spot one by appearance alone.
The main reason they were dangerous was because of their resilience. They needed to be killed in the larva stage since any attempt made on the cocoon would only make them resistant to that kind of magic in the future.
