Yari No Yuusha No Yarinaoshi

A brief description of the manga Yari No Yuusha No Yarinaoshi:

Have you heard of the Hero of the Shield? Well, one of the characters in the story, Motoyasu Kitamura, who is the Spear Hero, also decided to go on an adventure. Not only did he get the chance to breathe in before he died, but he also got the chance to avoid that outcome.

He cleverly directed the time stream in the opposite direction. Now he decides to take advantage of the situation. What does a hero need in order to reach new heights? Upgrade properly and throw himself into battle! But by a strange coincidence, it’s not an adventure action movie, but a comedy spin-off.
