During the next few years, Aisrin was encouraged by his family to practice his magic and teach it to his siblings. It wasn't easy at first, but Aisrin slowly learned each of his siblings' best magic affinity.
While he taught his siblings the magic he knew best, they taught him Forma magic, in which he had little to no affinity for. The most he could do was transform his left arm into a semi beast form.
"I'm sorry Aisrin, I'm not sure how to make it easier to think about. Maybe try to find out what kind of beast spirit you have? We are Fenris in spirit and have human intelligence. so we naturally have the ability to become human like. But you are human in spirit and mind." Samia offered. She was tge only one besides Sira who continued to instruct Aisrin in Forma magic.
"Hmm... No, I can't imagine any kind of beast spirit inside me." Aisrin replied after thinking about it.
"That's odd, you're incredibly talented in mana manipulation, but you can't manipulate it to transform." Samia pondered.
'Transform... perhaps...'
"Takeover?" Aisrin muttered aloud as he thought about transformations. The mana inside him swelled within and a familiar feeling overtook his body as his body changed. His skin darkened, black wings sprouted, his nails grew and sharpened into claws, and his teeth sharpened, some needle like and others became like a sharks.
His eyes became slitted with red irises and his senses sharpened. He looked just like he used to in his past life, the second one. Samia looked at Aisrin in surprise.
"You look just like a demon... I guess that's a success?" Samia questioned, she wasn't afraid, just intrigued.
"I don't think it is." Aisrin answered, his voice was even the same as his second life.
"Everything about you changed. The way you feel is even different. Your smell too. It's like you became an entirely different person! This is definitely a success!" Samia noted excitedly.
Aisrin turned and cast a fireball down the cave, away from the entrance. The fireball was large and took up almost the entirety of the cave as it shot through the cave. It's power and size was the same from Elrim.
Aisrin sighed and canceled the Takeover.
"I hate that feeling." Aisrin shook his head. Soon the fireball exploded deep inside the cave, causing tremors to rock the earth around the family.
"Aisrin! Stop destroying tge cave!" Frill scolded Aisrin not long after.
"Sorry!" Aisrin called back.
"Perhaps you have more of a dragon spirit?" Samia continued attempting to get Aisrin to learn Forma.
Aisrin was about to retort back, but a faint thought surfaced from deep within his mind, interrupting his previous train of thought.
"Maybe... but, I'm thinking it's something more... unique!" Aisrin suddenly exclaimed.
"Oh? Do you finally grasp the feeling? The feeling of your inner spirit?" Samia asked enthusiastically.
"Again, I don't think it's 'spirit'. More like understanding, or a type of knowledge." Aisrin replied. His thoughts migrating back to his first life. He had forgotten all about it when he reincarnated into these fantasy lives, but movies, television, comic books, and mythology presented plenty of influence for Aisrin to draw from.
"Okay?" Samia seemed stumped by his answer.
"Just watch. Perhaps I've cracked it finally." Aisrin focused his mana and used the image and information he had in mind as a foundation for the mana to build upon. Sure enough, the mana took hold and blossomed throughout his body.
Forma physically changed the body just like Takeover, but unlike Takeover, Forma was less magical. Takeover used Mana to add to the body. Forma transformed the idea into reality using mana to provide energy to the body as it transformed.
Aisrins flesh literally began to stretch and tear as he began to shift into the form he imagined. Needless to say, it fucking hurt. His bones cracked and shifted as new bones were added and others lengthened or reshaped.
His muscles expanded and stretched to fit the desired form. Claws replaced his nails, a snout grew on his face and his ears moved to the top of his head, growing into wolf's ears. His stretched and torn skin looking terrifying on the appearance, but pitch black fur could be seen in tufts along his body.
Aisrin began tearing at the skin, both relieving him and causing great pain as he did so. The skin once torn off, just vanished. His eyes remained mainly stormy grey the only change being flecks of pale blue, like lightning within the storm.
Aisrins clothes had long been shredded and he had also enlarged to a height of at least eight feet. His sense of smell increased abnormally, his eyes gained a few secondary sights that allowed him to enhance his vision to see in the dark, see far away objects as if they were right in front of him, and a slight x-ray that allowed for him to see through light and thin objects.
His hearing was majorly increased as well. Though he was still transforming, this knowledge seemed to download into his mind. Soon the pain subsided and the transition finished.
His family had surrounded him and stared in confusion.
"Well... at least you somewhat succeeded?" Sira thought Aisrin had attempted to Forma into a Fenris, but failed again.
"No... it's a success." Aisrin responded after a short pause of silence. His voice was still unchanged.
"Success?" Samia asked, bewildered.
"Yes. It's a... made up creature." Aisrin replied.
'Though it's not at all the same. X-ray vision? Maybe it did fail? Or my thoughts were too unfocused? The size is a bit much... And I'm naked...'
Aisrin looked down and checked his nether region, only to immediately cover it.
'Unlike Hollywood cgi, anatomy remains true to its nature... I wish I hadn't seen that...'
"What a peculiar child you are." Frill chuckled.
"Why don't you test that form out? Let's see what this... made up creature can do!" Jira joined in on the excitement. This got many excited responses from everyone, even Frill.
"Alright." Aisrin agreed.
*The forest outside the cave*
Aisrin was still getting used to the movements of his body. Being different from what he was accustomed to, he hadn't fully grasped the muscles he now had. Jira had changed to his Wolf form and stood next to Aisrin.
"Let's start with speed and agility. Test out the movements of your body." Jira instructed.
"Alright." Aisrin agreed. Jira shot forward at half his speed, easily distancing from Aisrin in a blink. Aisrin crouched down slightly, all his muscles constricted and released explosively when he lunged forward. The ground blew apart where he launched and he passed Jira as if he was standing still. Aisrin soon slammed into a tree, as he wasn't used to his body, but it didn't stop him. He just blew through it.
The tree splintered apart and toppled into other trees, breaking more and raining down branches and leaves. Luckily it stopped just before hitting the ground, leaving an obstacle for Jira to avoid. Jira had sped up to full speed, only barely catching up to Aisrin when he was slowed by the tree.
Both stopped shortly after. The next thing they did was jumping up into the trees, and attempting to navigate the treetops, but Aisrin launched above the trees and failed to land anywhere but the ground after smashing through branches on the way down.
Strength was unneeded for testing as he had already proved his strength. Durability as well. Though he enjoyed the experience, he also missed his control. So Aisrin called the test run off shortly after slamming into the ground after falling from the jump. The change back was just as agonizing but far quicker.
"It gets easier the more you do it, doesn't hurt as bad." Jira patted Aisrin on the back sympathetically.
"Sure... like I'll be doing that often." Aisrin retorted. The two returned to where the others were waiting.
"Had enough?" Frill asked. Aisrin was about to respond, but his x-ray vision activated randomly and he saw through her clothes and immediately got hard. Her large beautiful breasts and graciously inticing curves, that voluptuous ass and a slight glimpse of her tight looking, hairless pussy, imprinted into his mind instantly.
Thus passed his thirteenth year, that moment being both fruitful and embarrassing for him. He'd need to learn to control his new permanent, and extremely convenient, abilities. To avoid public embarrassment.
