SSS Beast Tamer : My Weakest Summon Is the Final Calamity

When the System descended ten years ago, the world adapted. At eighteen, everyone awakens a class and contracts their first beast. Motoyama Haru receives something that shouldn’t exist. SSS-Rank Beast Tamer. The highest rank ever recorded was SS. Then his first summon appears. A small black bird. Weak. Fragile. Laughable. The entire hall laughs. The Association flags him for investigation. Online, he becomes a meme within hours. But the System is glitching. His beast has no listed rank.Its evolution path is locked.Its data is corrupted. And every monster it kills doesn’t leave a body. It disappears. Absorbed. Haru didn’t want fame. He didn’t want power. He just wanted to survive. But the more his summon grows, the more the world starts to notice something terrifying. This isn’t a weak bird. It’s something sealed. Something that once devoured entire worlds. And if the seal breaks… The System itself may not be able to stop it.
