Run, I Have a Second Personality

While Kakashi worried that Jiraiya had gone insane from writing novels, what was Jiraiya himself doing?

Why had he been deemed to have disappeared after going out for a fling?

Jiraiya certainly had not fled to evade punishment.

After heading to the pleasure district, Jiraiya spent his days drinking, making merry, and squandering money recklessly.

Kashin Koji seized the opening and took the opportunity to commit his crimes.
