Rich Daughter Reincarnates as Her Eighteen-Year-Old Self to Rescue Her Younger Brothers! - Chapter 676 - : Anonymous Report

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

But why does a death looks like watching himself from the third person perspective? Is this the purgatory to watch over his own shoulders at the mistakes he made? A punishment for Mathew's sins to repeat those mistakes over and over again?

But wait, what are the three clocks in the corner of his vision, one of which only five minutes away from ticking out?
