- Description from novelbuddy

A 34-year-old NEET otaku, chased out from his house by his family, found that his life is reaching a dead end. He then recalled that his life could actually have been much better if he had made better choices in the past.

In a bustling modern city where ancient secrets and mysterious powers collide with everyday life, 22-year-old Ethan Cross seems like your average college student. Behind his unassuming demeanor lies a man shrouded in secrets—a masked vigilante known only as “Virtuoso,” feared by criminals and sought after by powerful organizations.Ethan is overpowered, sarcastic, and ridiculously skilled at everything he does. But there's one thing he’s terrible at: romance. When the enigmatic and fiercely independent Mia Harper stumbles into his life, she unknowingly becomes the key to unraveling a conspiracy that ties Ethan's past to an ancient prophecy.Between laugh-out-loud moments, explosive action, and unexpected twists, Ethan navigates his double life while trying to protect Mia, keep his identity hidden, and maybe—just maybe—figure out how to confess his feelings without being a complete disaster.
