Demons and Beast descended, terrorizing the whole world for the past hundred years. Everyone can awaken a grimoire and summon a beast during their age of ceremony. Lucas, awakening the weakest grimoire, also awakened the weakest beast- a small dog with no combat capabilities. Fortunately, as a transmigrator, Lucas also mysteriously awakened a system that allows him to evolve his summons into their mythical beast counterpart. Follow Lucas and his journey to greatness as he evolved his beasts into never been before seen mythical creatures.
Where to find such a beast, though, was another problem that he was not in a hurry to solve.
The first beast that was granted to the summoner was somewhat random and based on the grade of the grimoire. However, for the next and upcoming beasts, the summoner had the freedom to choose as long as it was within the limits of the grimoire.
As an Unranked Grade grimoire, Lucas' grimoire could only allow him to contract with Unranked Grade and Iron Grade beasts at most. The strength or the star-rank of the beast that he contracts should not exceed his own star-rank by a large margin; otherwise, the contract process would fail and it might cause him some backlash.
Lucas did not want to hastily choose his second beast. He wanted to plan it very carefully to avoid uncertainties.
