Yang had started her training at eight since her preferred weapons were god given right from birth. this was to say her fist as she kept bothering tye to train her until he relented and agreed. leon's sharingan had evolved to two tomoe during these two years after he had seen ruby get picked on by some other kids while they were out and about and he grew very angry. this change didn't get unnoticed by tye and summer who were worried that his eyes grew stronger when he was exposed to extreme emotions.
The new form of his sharingan was not just far stronger than before but it also gave him access to the perfect memory that the yes were well known for. this made him a nightmare to teach for summer since he just needed to see something once to remember it perfectly. add to this his powerful imagination and comprehension ability and he learned at speeds that left one breathless. leon didn't need tye to train him unlike yang but his biggest issue was that he didn't know what weapon to choose after learning about the multiform weapons.
The biggest issue with most weapons was their reach but thanks to the multiform weapons having guns built in this problem was gone. leon needed to figure out what weapon was the best suited for his unique build which included his wings and tail. after thinking about it seriously for about a week leon decided to fuse two different weapons with similar styles together , the scythe and the spear. the reason for this decision was that spears excelled at stabbing things while correct usage of a scythe could grapple and slash with great precision. mix these two weapons together and you get a weapon that is hard pressed not to be a pain in the ass to counter.
The way leon went about creating his monstrous weapon was by using his sharingan to memorize the entire vale libraries selection on engineering , weapon creation and forging. after spending two days digesting the information leon got busy sketching the weapon in all of its forms while working out the kinks in the design as he did so. the gun was easy to set into the weapon as he had most of the shaft to work with. the biggest problem was seamlessly transitioning from spear to scythe without ruining the weapons structural integrity.
The solution to this was a special grip on the shaft that he could work to activate the mechanism inside the weapon that switches the one foot spear blade to the two and a half foot scythe blade that was thinner since its purpose was different to the spear form. the functional engineering done leon focused on making the weapon as intimidating as possible adding thorns of metal for appearance in places that doesn't hurt the functionality. at the joint where the changing mechanism was located leon added a metal grim mask of his own design that doubled as a small shield in a pinch.
The final weapon looked pure evil in all of it's forms suiting the devil persona he wanted to adopt. the entire weapon was collapsible as well making it far more portable for leon and he now needed to get the materials for the weapon. thanks to the sack of loot leon gave to tye and summer for an equivalent amount of lien leon had just barely what he needed for his weapon. knowledge is great and all but when leon actually tried creating the weapon he came across difficulties in the form of a lack of skill.
Many curses and a few naps later and leon finally finished his frankly horrifying weapon and it fit him perfectly. next came actually training with the weapon and loathe as he was to admit he actually needed qrow to come back to figure out how to use the weapon fully due to the super fine attention to detail scythe work required. it took a month for leon to familiarize himself with the weapon and two years to master it. summer had left on a mission during these two years and word of her perishing in an ambush came back.
The sadness leon felt at the news was enough to push his sharingan to its mature form with three tomoe. everyone was at a low point for months after that but qrow and tye both put aside their own grief to take care of leon and the girls. leon was the biggest worry for them after his eyes evolved as he had began to fly off early in the morning and only come back late at night with his weapon showing a huge amount of new battle scars. the fact that leon was literally glowing red with life force told them exactly what he had been doing and it wasn't a healthy outlet.
