Lost Cause (слэш)

Izuku Midoriya disappeared on the night of the encounter with the Sludge villain.
A week later, he was declared dead, and all search efforts ceased—a usual fate for a quirkless nobody.
Several weeks after that, his case was reopened due to the appearance of a new vigilante in Musutafu. A vigilante with an astonishing ability to vanish without a trace. What sets this one apart from the majority of vigilantes is that he's only fourteen years old and doesn't hide his face. No, Izuku Midoriya was starting to become known for his nocturnal activities in the city. The question was... Where did this quirk come from? Or where was he most of the time when he wasn't breaking the rules? Or why wasn't he hiding his identity? Or why did he refuse to go back home and also declined Eraser Head's help?
Izuku Midoriya was a complete enigma. And like any good mystery, he had to carefully guard his secrets. Because once the truth was known, his entire life would shatter forever.
Or perhaps it already had, and Izuku simply wasn't ready to admit it.
Or, in the end, maybe Izuku did possess a quirk with an unusual activation. Izuku is a ghost who dedicates himself to fixing others' lives but not his own.
