Okay, let's recap. So far, we know that there have been two transmigrators.

First, we have Batman. He destroyed the moon. Yes, he replaced it so all he did was destroy any chance of Madara's plan succeeding. Due to his actions, Akatsuki might not exist. We also don't know where Zetsu is.

Second, we have Gojo Satoru. His effect is felt more strongly. He destroyed all the tailed beast except the one tailed. This means Naruto would have a much better childhood but it also means there might not be someone strong enough to protect the world.

Shit.

This was not what I signed up for. This was supposed to be a nice vacation. A smooth ride collecting various resources on my way to becoming the greatest ninja on the planet. Now, I can't rely on that anymore. Since I have no idea what's coming, this world just became a lot more dangerous.

I have to get strong enough to stand among the monsters of this world. I'll have to do it on my own merit. Burning with the fire of my determination, I was pumped when my first lesson with Kurogane-sensei began.

"First things first. There would be no fuinjutsu lesson for you." Kurogane-sensei said. "You failed the challenge so you'll have to live with the results."

We were standing in his training basement. The ceramic plated walls were covered in enough fuinjutsu seals to choke a giant snake. "There are different types of ninja techniques but I would be teaching you the three main types. Ninjutsu, Genjutsu and Taijutsu."

"Due to your unique coils, elemental ninjutsu is out of the way for you. Fortunately, not all ninjutsu are elemental. An example is the body replacement jutsu you learnt. Genjutsus are hypnotic techniques that directly affect the mind and indirectly affect the body."

"Today, we'll be starting with the most important ninja discipline. Taijutsu. A ninja without a solid Taijutsu is like a baker without flour. They should both quit their profession because they won't last long against their competitors. Whatever you do, never slack on your taijutsu, understand?"

I nodded.

"What is Taijutsu?" He stared at me.

"Martial arts?"

"Close but no." He chuckled. "Martial arts are spiritual and meditation techniques that require chakra. Taijutsu is an attack technique that uses physical strength and stamina to deal damage without the use of chakra. Remember Taka. The power you get from your taijutsu depends on the training you put in."

"Yes sir."

"We'll be starting with the foundation of all taijutsu. Footwork. If two ninjas with equal proficiency in taijutsu do battle, the one with the superior footwork wins." He gestured towards the barrels sitting nearby. "To test your footwork, I'll be tossing these blunt shurikens at you. You must dodge them without chakra and without jumping into the air. Ready?"

"Yes sir." The first shuriken spun towards my face before I even finished speaking. I ducked to see another shuriken hurtling at my face. I rolled to the side.

"Now rolling on the floor either." Kurogane-sensei's voice reverberated through the room as he sent two shuriken at once. I stepped to the side and another two shuriken were waiting for me. I dodged one but the other hit me on the shoulder. I swallowed a cry of pain.

"Experience is the best teacher Taka. Don't dodge blindly. Predict where the next shuriken will come from." He kept giving me advice as I focused on evading the spinning harbingers of death. "I can read you as plain as day. Your body betrays you. I know where you'll be before you get there."

We continued training and before I knew it, a month was gone. I was taught a taijutsu form that was tailored for spinning around while fighting multiple opponents. Every day, I visited the basement for training. Sometimes sensei was there other times, he was out on his ANBU duties.

On a certain morning, we stood facing each other in the training basement. "You've improved. Well done. I know you're building a style that revolves around shuriken so, today, you'll be allowed to fight back. We'll both try to hit each other with our shuriken. To make things easier for you, I won't move from where I'm standing. Let's begin."

He didn't have to tell me twice. I sent a hail of shuriken at him and all he did was crouch as they sailed overhead. "That was terrible." He chuckled. I sent another wave at him from different directions. All he did was to send shuriken to deflect every one I threw at him. He yawned. "You'll have to try harder than that."

Training with sensei was an exercise in brutality. There was no rest. You either fight or you get turned into a pin cushion for blunt weapons. Before long, sensei leveled up my taijutsu training. I had to fight him with my taijutsu style in close combat while using shuriken, a ranged weapon. Even if I never scored a hit against him, I could feel myself growing stronger. Whispers of my genius were already filling the academy grounds.

Three months later, sensei began my lesson in genjutsu.

"Genjutsu are all ninja techniques that affect the opponent's mind using chakra. Genjutsu involves dragging the mind of your target into an illusory world. You can use it to affect the target's senses. Genjutsu has two major disadvantages. First, frequent use can cause exhaustion. Second, genjutsu cannot inflict physical damage. However, genjutsu is perfect for infiltration. Stand." We both stood. "Before you learn your first genjutsu, you must first be proficient at dispelling it. I'll be using a genjutsu to mess with your balance."

He made a single hand seal and the world began to sway before me. "Kai!" I flared my chakra and dispelled the jutsu.

"Flaring your chakra in an enemy territory can give away your location even to non sensors. You'll be learning how to dispel genjutsu without speaking or letting your chakra escape your body. Ready?"

I nodded. As training went on, my fear of the sharingan increased. People out there can do this just by looking me in the eye. With two transmigrators already changing things, there's no guarantee that the Uchiha clan would be destroyed.

I need a defense against the sharingan.
