■About TV Anime Let This Grieving Soul Retire!

Let’s become treasure hunters.

Only one goal in mind: to become the strongest heroes in the world.

 

Among the six who once made such a vow, there was one boy who utterly lacked talent.

One day, his childhood friends said to him “Krai, since you don’t really have a role, you should be our leader.”

Formed by monstrously talented freaks (=his childhood friends), the party known as the “Grieving Souls” made its name known throughout the imperial capital in just a few years. And Krai, who was enthroned at its pinnacle, was quickly feted as the leader of the strongest party.

 

 

Misunderstood by the rising expectations of those around him, his actions always led to unforeseen developments…

This is an epic tale filled with glory and agony of the leader of the strongest party and the most formidable clan master, Krai Andrey!
