Kaiju Jiu You Wangzhe Zhanghao

By the year 2063, Earth has basically become one giant game — except dying is real and strength determines whether you eat or starve. Ye Hao is a high school student stuck at level three while everyone around him is climbing the ranks. He's falling behind, his family's struggling, and the system doesn't care. Then he accidentally activates something called the King's Account, which is essentially a legendary upgrade system that shouldn't exist, and suddenly he's not the kid everyone overlooks anymore. The first couple episodes do a good job setting up how desperate things are before Ye Hao gets his edge, so the power shift actually feels earned rather than handed to him. From there it's monsters from other dimensions, family drama, and the slow unraveling of something much bigger happening behind the scenes. This is a 12-episode ONA based on a web manga, produced by Liliyabi Company Introduction, and it leans hard into that gaming-mechanics-meets-real-world-stakes setup. If you liked Sword Art Online's premise of games bleeding into reality but wanted something more grounded in survival, or if Overlord's overpowered protagonist angle appeals to you, this hits a similar frequency. It's got some Log Horizon DNA too, in the way it treats the game systems as actual societal infrastructure rather than just a backdrop. Worth the time if you're into urban fantasy with a power progression hook.
