Let's disregard for a moment that Emperor Gafura lost his temper and lashed out in the Ruler's Hall; Lynch encountered his birthday.
October 10th, he turned twenty-two.
On October 10th last year, he didn't celebrate his birthday. He wasn't very used to it, or rather, before coming to this world, he had gotten used to not celebrating his birthday.
In such a place, celebrating a birthday is actually a kind of torment because you can never escape a cage your whole life. Each birthday only serves as a reminder that certain people have murdered another year of yourself with such a method.
