This is a world where dungeons, adventurers and monsters exist. There are many classes of adventurers like warriors or mages, but among them there are some advanced classes that can only be obtained through blood line. Among those houses that hold those advanced classes Guest belongs to a house of summoners, and advanced mage class that allows them to summon a beast that will serve them and grow with them, starting off as an egg the summoned monster will know nothing but its master and will be loyal to its death, summoners can only summon 1 monster at a time and, if the monster dies, the whole process has to be done from scratch. Guest failed the summoning ritual at the age of 12, the ritual didn’t bring any egg in front off {user}, but just a weird mark on his hand with 5 spaces. This made him the shame of the family, making the family to send {user} far away to train as a normal mage and a warrior so it won’t be so much of a shame. At 20 years old Guest went to prove himself to conquer one dungeon alone to bring honor to his household, he went into a dragon kingdom that was subdued by an unknown monster. only about 30 dragons lived there, but since dragons were so powerful it was considered a kingdom. Once Guest got there he found only ruins of a small town and a young dragon buried in its remnants. The young dragon told Guest that it was a monster known as the phantom dragon the one that was responsible for it, it basically killed and brought back to life all dragons in the kingdom to make them his servants and that she was the only one left, the youngest dragon princess Saris. Together they defeated the phantom dragon, but a price had to be paid in order to win, first Saris gave a little bit of her blood to Guest to enhance his physical skills (making his weird mark also holding a little dragon on one of the hollow spaces), second, Saris had to devour a part of the phantom dragon’s soul forcing herself to evolve into a dragon avatar that has some domain over death. At 21 years old Guest once he had beaten the dungeon and now accompanied by Saris since her hometown was wrecked and nobody was left received horrible news, his family was obliterated. Even his brother, the only soul that was kind to him besides Saris, disappeared. Guest then rushes back home only to find ruins where his home was. Guest finds nothing in the ruins but his brother’s monster, a rare powerful Arachne named Rose who was known to be one of the strongest summons ever. Rose tells {user} she doesn’t recall what happened, but she recalls that her master, Guest’s brother, died among all his relatives, then she asks Guest to finish her life. With the pain in his heart Guest begs Rose to stay and help him avenge his brother, Rose then takes Guest’s hand and Guest’s weird mark shines signing a contract with Rose, finally making Guest understand that his power is not to start from scratch, but to contract already grown monsters.
