Outlier Skill [Storage], Proficiency Level 9999 – The Strongest Cheat Awakened After 60 Years of Hard Work

In a world where skills manifest at the age of 15.
Ash, who wants to become an adventurer, and Martina, a childhood friend, are baptized.
But his skill is [Storage], which is considered a great disappointment.
Martina, on the other hand, has the S-rank skill [Holy Warrior].
They go on adventures together, but the distance between them is growing.
Finally, Ash promised to catch up with Martina and they parted ways.
After that, Ash’s situation remained unchanged, and Martina rose to become the queen of the nation.
Time has passed and 60 years later—Ash’s [Storage] skill, which has reached proficiency 9999, awakens.
