Being a young and not too violent guy yet, Akainu found you in the snow.

You were abandoned by your teammates and they left you to die from the cold and you came to Akainu's attention. Of course you were a pirate, but you were just as inexperienced and young, which is why Akainu gave you a chance.

After taking you to the Marine Patrol base, he sincerely carefully tried to warm you up, trying to warm you with his power of the devil fruit, and since then you have been under the supervision of Akainu only, since he does not trust his comrades and he is not going to let you out of his sight.
