Next day,
Blaize woke up in an infirmary. He felt uncomfortable and exhausted. There's also slight pain in some parts of his body. Cracking his head, he recalled yesterday's events.
'The consequence of overusing the devil fruit power is too great. My strength isn't strong enough to handle the repercussion, I better refrain from rashly using the devil fruit powers.' Blaize thought.
Even so, he felt some changes in his body. With a thought, the system interface appeared before him.
[~ Name: Blaize Hunt
Occupation: Marine
Constitution: 5.4 [Strength: 5.5, Speed: 5.4]
Devil Fruit Potential: 5.5
Haki: None
Items in storage: None
Free attribute point: 0
Tasks: Currently none ~]
His attributes have increased. Even though it's just 0.1, the change was there. Fighting Garp without holding back had possibly unlocked some of his potentials. It confirmed Blaize's previous guess, battling is a good way to enhance his strength faster.
At that moment, a tall, broad man wearing a doctor coat, chewing a fishbone arrived. Blaize recognized him as the marine doctor — Fishbonen.
"Oh! You woke up so soon. I thought it would take another two days, you have an excellent physique." Fishbonen commented. He wasn't praising but telling the truth.
When Blaize was delivered to the infirmary, he checked his condition so he knew all about it. Even though he wasn't injured, his muscles were completely worn out as if someone squeezed a lot of life energy out of them.
"Your condition is nothing serious. Eat a lot of nutrient foods for a week and you will recover." Saying some comforting words, Fishbone left the small room.
Just a few minutes after the doctor left, Garp came over. "Brat, you woke up!"
"Yes!"
"You are pretty strong for a ...eh? How old are you?" Garp asked, seeming pretty relaxed and nonchalant as ever.
"Will be sixteen in another 3 months."
"Good. Why did you want to fight me? I think it's the first time we had met."
"Who wouldn't? I heard you are the only person in marine who fought Pirate King Gold Roger on par when he was alive.
I want to see how far the gap is, between me and the blazoned late Pirate king of the sea!"
Blaize's reply jolted Garp for a moment before he laughed aloud. "Bwahaha. You are pretty funny for a hairless brat. Even so, Why did you join Marine?"
"To become stronger." Blaize gave a candid and instant reply.
"Why do you want to become stronger?"
"To fight the strongest, you have to be stronger." His reply stumped Garp but it was in line with his personality so he didn't question further.
"Let's go out. What you need isn't rest but a lot of grilled meats." Garp stated. Blaize agreed with Garp on this one, so he climbed out of the bed and followed him.
"What is your devil fruit power?" Garp asked.
"I don't know. After I ate a weird fruit, I gained the ability to control and manipulate heat to varying degrees.' Blaize replied.
"Are you sure?" Garp asked.
"Yes. Why?"
"Nothing. I heard the heat-type devil fruit was already eaten. So we don't know what type of devil fruit you ate. Only knowing the type of devil fruit you ate, you can improve it further."
"Oh!" Blaize exclaimed but thought in his heart, 'So Charlette Oven already ate the heat-heat fruit.'
"I was meaning to ask you, brat, how did you predict my movement yesterday? Is this related to your devil fruit ability?"
"Yes. By releasing heatwave, I can sense everything within a meter range." Blaize told without concealing anything while Garp nodded his head in understanding.
Garp then led Blaize to a training field and requested, "Show me what your devil fruit can do. But, don't overuse it like the last time, just a simple demonstration will do."
"No problem. But first, I need to recover my physical strength. I haven't fully recovered yet." There's still exhaustion in his body. With that, he won't be able to display his might.
"Ok. You go and fill your stomach. I will call Sengoku, I have a nagging feeling your devil fruit isn't as simple as you portray." Garp told.
'This old man possesses a terrifying instinct.' Blaize silently mused. He wants to keep his devil fruit ability mysterious, otherwise, he wouldn't mind revealing the name of the devil fruit.
--
30 minutes later, Blaize met Sengoku and Garp in a training ground located in a remote location. He could tell the two of them want to keep whatever he's going to show as a secret. It coincides with his intention.
"Admiral Sengoku!" Blaize saluted the latter with respect while Sengoku nodded his head with a slight smile.
Sengoku liked Blaize's personality and disposition as soon as he met him. He's calm, confident, and energetic with a trace of a smile on his lips. From him, he felt a strong positive feeling.
"I heard about your devil fruit power from Garp. Let's find out how your's different from the Heat-Heat fruit." Sengoku stated as he's also curious about the unknown devil fruit.
Walking to the center of the training field, Blaize explained the abilities of heat manipulation: Blazing Fist, heat Sense, heat Blast, heat breath, heat Beam, and so on.
Just as he finished, he raised his right hand. It glowed in fiery red, and the color slowly changed from bright red to pure gold. At that moment, even the temperature around them began to rise and affect the surrounding.
Blaize quickly controlled his heat ability and reduced the temperature of his hand to normal. He then showed the ability of heat blast. A strong, scorching heatwave discharged from his body and spread in all directions.
This kind of ability won't help him in fighting against stronger opponents but it can take out a group of weaker ones.
"I'm experimenting with the extent of the fruit powers, so I still don't know for sure." Blaize shared his thoughts.
After 10 minutes of presentation, Garp and Sengoku also came to a conclusion. His fruit isn't as powerful as they thought but it has limitless potential. It's in Blaize's hand how he improves it in the future.
"It's clear your devil fruit is different from Heat-Heat fruit. I think it's some kind of special paramecia that's unknown to others." Sengoku stated. "It's a good devil fruit ability."
"Thank you, Admiral Sengoku. I too think my devil fruit ability can get stronger with me." Blaize told and vaguely revealed some of the fruit's abilities; explosion and fire manipulation.
