*** FLASHBACK ***
Pushing his younger sister's wheel chair while roaming around the beautiful hospital garden.
The dark-haired {-Diamond-Ranked-} hunter became worried at the silence of his younger sister.
"Are you alright? Should we go back inside?" Joe became concerned with his younger sister's condition.
His younger sister wore a pink bonnet to reduce the apparent look of her hospital clothing.
For Joe's younger sister, the bonnet would make her feel less sick and look more normal than the usual terminally ill patients in the hospital.
"Yes, I am alright. Don't worry too much. Just keep pushing the wheel chair and let me do the thinking," the response of Joe's younger sister to him.
It made Joe feel a bit relieved that his younger sister feels better.
"Then why are you unusually silent? What's going on around in that smart head of yours?" Joe curiously asked.
