He had crafted his mother, to the best of his current abilities. A chakra conductive metal kitchen knife. Sounds pretty expensive, and dangerous? Well, it was.
Mind you, she was known for her speed. Imagine standing there, takin' a piss, and then next thing you know your throat's cut. Just that easy for his Mother, a terrifying woman...
Why not arm her with a blade that could clash 'hopefully' against some of the failed swords before the perfected seven swords. Did he ever mention his mother is a Lightning release specialist?
No? Weird, almost like he was secretly making his already frightening mother, stronger... Strange.
His father on the other hand actually got something he desperately needed. It was a book, the title of said book being. ''How to notice the signs of your wife wanting a second kid. Before she kills you in your sleep.''
Written by yours truly, but he had used a pen name for the book. 'Sugma Nat' The first word being pronounced exactly how you think, and the second being pronounced like the Japanese say 'Nut'. He was shameless in his debauchery.
His mother was thrilled to have the knife, when she asked where was the gift for his father, he said it was still being delivered so he couldn't get it right away.
Only his father knew what the gift was, and he was visibly uncomfortable at the sight of his wife now owning a chakra metal kitchen knife... Was Rei right? Was she showing the signs? He would need to study this in-depth, more so than he ever cared about the academy.
Having been feeling in a 'Gifting' mood, he gifted Tobirama a pen, with refilling ink using a rather simple induction of seals that turned ambient chakra into ink. While also being able to make it copy his movements.
Basically meaning if he were to use his perfect chakra control, he could control the pen without moving his hand, it also meant that if he channeled certain types of releases, the ink would not only change in color, but depending on his fine-tuned it was, it also meant he could make some types of inks simply vanish, only to be viewed if the person who received the letter knew not only the level of chakra but also the correct fluctuation to get it to show.
The Might family received not only the way to make the seals, but also green jumpsuits that came pre-equipped with settings on gravity and even reverse settings. Making them able to jump higher, move faster, the like. He got to see Dai laughing in jubilation while bouncing around the room like he was on the moon.
Mito, his beautiful fuinjutsu teacher got a hairpin, that channeled ambient chakra into mystical palm energy, at first she was confused as to why he gave it to her, but after he explained the application, she demanded that she teach him, and in return for all money she makes off it, she'd have a 40 - 60 split with him, him having the forty.
The hairpin was actually pretty simple. By having that very gentle mystical palm energy circulating near the face, it would keep the skin beautiful and soft, preventing scaring and even helping prevent wrinkles earlier than they should appear.
Of course, there was also the combat use, this hairpin even if very weak, could help hear minor cuts and small bruises faster than most people naturally healed. He had gifted a free one to Mei's mother, and Orochimaru's mother.
Though, how many of the people who would buy these hairpins would care for such a minor combat boost? We all know why he would soon become filthy rich... again?
Kakashi and his father both got specialized protectors. Basically the same as the hairpin, but also having the effect of helping them not only break genjutsu, but the calming effect of mystical palm would be great in a serious situation.
Rei wasn't skilled enough in seals yet to make this much more powerful than it was without using more expensive material, and learning how to 'Over write' runes as well. Basically being able to write multiple layers.
He could, but the mystical palm ambient gathering was a very complex ruin.
Tobirama actually asked Rei if he would want to be a part of the science division of Anbu as well. A fancy-sounding term, but it was basically just nerds, doing nerd things. He agreed to join and was given a small group of scientists that could help him, Orochimaru's clone was actually a part of this small group. With Orochimaru's family still fine, and his kink for immortality out of the way, he was actually a great person, great at conversation, a great friend.
The only weird thing is he licked his lips and smiled really creepily when he was either excited, nervous, or happy. Turns out? It was a family trait as his mother did it as well, but when she did it it was those hot, scary 'Ara~ Ara~' vibes. Rei thanked himself for being young, his little brother didn't get confused when he saw it and for that, he was thankful.
Turns out that the Nara had always been well known for their minds, due to their increased rate of Yin release, a lot of them were brilliant, all be it lazy. Rei had gifted the Nara head a Shogi board that moved on its own depending on the chakra movement of the two players. Shimaki, the current Nara head as well as Shikaku's dad was thankful for it, not only did it train early chakra control, but it helped to train the young generations more techniques with their famous shadow control.
Rei gifted himself as well, and he did so by shattering a perfectly good Odachi sword.
