Online Game: Starting With SSS-Ranked Summons

"Earthlings, you are called upon to partake in the Universal Doomsday event..." The announcement echoed worldwide. "The initial batch of beta testers is now open! A total of ten million spots have been allocated!" The news hit hard, especially for Arthur, a young man living in the slums. "Talent Activation!" Arthur exclaimed, startled by the system's response. "System Error!" Confusion washed over him. "Unparalleled Talent: Primal Summoner," the system declared, leaving him bewildered. He had expected to command a formidable ancient beast to aid him, not this... "ISummoned a Kitten!" Arthur cried, staring at the adorable feline before him. As the game merged with reality, Arthur found himself surrounded by legendary summons to combat the forces of darkness. "You have summoned the SSS-Rank 'Primordial Dragon'!" "You have summoned the SSS-Rank 'Belzebub'!" "And you have unlocked the SSS-Rank Skill 'Berserk'!" Each revelation left him stunned and uncertain about his new role in this grand adventure.
