Within the dead of night, all light within her family home switched off with the other soul, her son, presumably resting, Miwa took to stand dead in the middle of one of the manor's gardens. She chose the one with flat land, thinking this would be a good place for her to get to work.
Hair tied back into a pony tail and clad in a vest top, trousers from her Shinigami uniform, in which her vest was tucked into the elastic band at the top of the trousers while the bottom ends were tucked into the top of her socks, making them look like normal jogging bottoms with slipper pumps ending her outfit, Miwa stood in silence, holding her sheaved Asauchi. She closed her eyes, inhaling and exhaling calmly before taking off her glasses. Holding them out in front of her, she slowly opened her emerald eyes, adorning a relaxed but serious expression. Flinging her hand upwards with the flick of left her wrist to softly throw them into the air, not too far up, Miwa unsheathed her blade with speed, whipping it in front of her with one of the flat sides facing upwards, just in the nick of time to catch her glasses.
Clearly this was not her first time training in any sort of way, in fact she did so often even before Kurisa died. It was after Kurisu's fiancée had passed away, leading to other events in which Kurisu had no choice but to flee, and with Kurisa spending almost all of his time at the Seireitei working, Miwa was left all alone. She wanted to do something productive and useful, so at first she incorporated techniques to improve her speed and accuracy with everyday housework. Soon she felt that it wasn't enough, there was no point in being half-arsed with it and might as well of went all the way. This came to her researching and observing other's training within the Gotei 13, her Squad Twelve position helping her gain the information she wanted much easier now. It came to the point where she was trying to teach herself to control her spiritual energy and use it in certain ways, which obvious took a long amount of time and more time to come, however she wouldn't stop and never will. Not until she's laying on her death bed.
Tilting her sword slightly towards the left, her glasses slid gently drown the edge until they expectantly stopped as the right hinge of the frame, since the glasses were still open, caught on the sharp edge of Miwa's blade. Eyeing the apple-green coloured glasses, with a slight flick of her right wrist, the glasses jolted into the air about an inch away from the blade's cutting edge. At that precise moment, Miwa swung her blade upwards with not much effort but impressive speed, meeting the right hinge momentarily as the blade cleanly sliced through it. As the main part of her glasses continued to fall, aiming to reach the ground in a handful of seconds, Miwa twisted her body a touch before bringing her sword diagonally downwards, producing a clean cut straight through the bridge of the frame while displaying her speed once more. It was only then did Miwa return back to her original stance and let the her glasses hit the grassy floor in three pieces.
Since it was the middle of the night, Miwa's vision was worse than it usually would be, however it wasn't too bad, only a tinge blurry so she could still see enough for her. Looking down, she crouched to pick up the pieces. 'Mustn't let anybody hurt themselves due to me leaving these here. ' Turning around, she was reminded of something else she had been meaning to test for a while. 'Shunpo.'
Disappearing in the blink of an eye, Miwa reappeared near the door to the manor. Not too far from her previous position, but far another to smooth a small smile across her face from the noticeable improvement. 'Well, that went better than last time' Looking down at her left hand, Miwa decided to just place her broken glasses onto the floor near the door, she'll throw those away later. Turning back towards the flat land, she bent her knees and took a moment, the smile dripping off her face as her features slowly grew serious. A second later, she darted towards her previous spot, unsheathing her sword once again to hold it in her right hand while her sheathe in her left.
Once she had reached her spot, Miwa flung her body into the air and kicked the space in front of her a few times, imagining a faceless person's body in front of her to get a sense for where her kicks would land; one in the right side of their ribs, another on the left side of the neck before flicking another kick immediately after in the left side of the hand, and finally sending one last but forceful kick to the right shoulder. Tucking her legs in, she spun her body around, swinging her blade to slice whomever would be close, just before landing in a crouched position. Imagining that she was surround by a circle of people, she slid between one of their legs, swiftly turning back before slicing her sword upwards as she stood, effectively chopping that imagined person in half. The next four imaginary people dived towards her, in which she took a step back to create a little more distance and time to ready herself in, soon dodging and countering all of their imaginary attacks while thinking of all of her possible openings at all times and how to defend them if need be.
Due to her vision being blurry and the sky dark with any light scarce, it wasn't difficult for her to imagine her faceless enemies and in-vision them in front of her while engaging with them in a fight. That was one of the benefits of training at this time to her, but her main reason for doing so was because she didn't want Kurisu finding out what she was doing. This was why she tried hard to minimise her noise and hold her energy down. It proved to be a challenge for her, which she embraced.
Focusing on her speed and force, Miwa hardly made any noise at all, only breathing steadily as she became a moving blur in the night. The only sounds being of her sword slicing through air and her feet gliding softly across the grass.
