Ryōsuke Hanyu has always had a strange obsession with volleyball. Ever since he first saw a match at five years old, that light ball—just 260 grams—struck his heart with the force of a thunderclap. From that moment on, he knew this was his sport. Now, after graduating middle school, Ryōsuke has transferred from Tokyo to the legendary Shiratorizawa Academy—home of powerhouse volleyball. But he didn’t realize Miyagi Prefecture was called the “death zone” of volleyball for a reason... With a sharp tongue, intense drive, and absolutely no clue how attractive he is, Ryōsuke is about to crash into a world full of top-tier players, overenthusiastic senpais, and high-stakes matches.

Vikter understood that his past was anything but happy way before he could even remember the sound of his mother's voice, but that doesn't concern him because he was living a happy life now. One where he loved and cherished his adoptive grandmother, where he had a friend close enough to be a brother, and his days filled with sun as he hunted game for his village. At least until a Knight arrived from the Eastern Empire. The new arrival was mesmerizing, until he began to destroy the village and Viker is thrown into a continental war where it seems that his only option is to get stronger, and maybe something greater as he explores the new world.

Kyle broke free. Sadly, punching the leader of a gang of thugs had consequences, and the leader's cronies would beat Kyle to death. But so what?! He didn't regret punching this guy even once! However, a powerful Magic Lady saved Kyle and then did something strange. She offered him a job. Apparently, he would have to go to a different world, a brutal realm where strength was the only law, and become its Overseer. A world where one person could fight thousands of people. A world where gigantic beasts broke mountains. And Kyle? He was just some random guy. He couldn't break mountains. Hell, he could barely fight a single guy, but what was he supposed to do? Reject the offer and get killed? Whether he liked it or not, he had to grow stronger, and while the beginning was tough, he actually found something he really enjoyed. His gigantic hammer. It was exhilarating when beasts exploded into chunks of flesh whenever he struck them. He loved turning boulders into rubble. With his hammer in hand, Kyle would forge a path of destruction through beast hordes and any ancient gods who dare stand in his way. And as his power grew, he became more and more involved in a war between two fundamentally different forces of nature. Join Kyle on his journey to become the Strongest Hammer God! -- Hammer starts at chapter 36 2 chapters every day. Join my Discord: https://discord.gg/EfePH46Aru
