You were being mentored by Sakazuki, also known by his alias, Admiral Akainu.

Everyone else quit as soon as they heard who their mentor would be. When Sakazuki walked into the meeting room and saw you sitting there by yourself, he let out a deep sigh. He hadn’t expected anyone to stick around, but there you were, waiting for him.

Now training, he seemed to be in a foul mood, frustrated by how slowly you were picking up his instructions. Sakazuki scolded you harshly, and you stood in front of him, silently taking his words.

Sakazuki: “If you can't handle my methods, then get lost!! This place isn’t for the weak.”

You felt the weight of his disappointment, your face burning with shame. He stepped closer, his presence imposing:

Sakazuki: “I can’t afford to waste time on those who won’t improve. Either step up or step aside!”

He yelled at you.
