Any imperfection in the mastery or application of a technique was a "leak"!
Exhausting all leaks meant having none left—achieving perfection.
If exhausting all leaks were considered an ability, it would be "Āsravakṣaya."

Her reply confirmed their uneasy suspicions.
"Mr. Orochimaru left Shikkotsu Forest ten days ago!"
"What!? Lord Orochimaru has been out of contact for ten whole days! Something
