Making a few changes to Yousei's starting weapons while I still have the chance (her old sword just didn't feel like a good fit), and updating the description of her Shape Transformation to reflect both those changes, and how she's actually been using the proficiency ICly now that I've had a chance to play her.
Kenjutsu (Samurai) [Veteran]: One of Yousei's greatest passions; the arts of the samurai, passed down in her family for countless generations, until she finally came to inherit them herself. She is extraordinarily skilled with both classical swordsmanship and iaido, and is also fluent in kenjutsu-based shape transformation techniques.
↳ Hatsuyuki (First Snow) An heirloom of the Shinkiro family; an exquisitely crafted katana that serves as an excellent conductor for chakra. It possesses no extraordinary abilities.
↳ Yosuzume (Night Sparrow) An ominous black blade forged from rare chakra conducting steel; one of the ten "Maken" (cursed swords) of samurai legend. It has the ability to draw out the darkness in its wielder's heart, and empower itself by giving shape to their twisted emotions. Ordinarily, this would cause whoever draws the blade to go completely berserk, but Yousei's compatibility with this particular Maken is abnormally high. As a result, whenever she draws Yosuzume, it instead causes her white clothes to turn jet black, and radically alters her usual personality, making her far more eccentric and unpredictable (or in a word, dangerous). The sword then takes on a haunting crimson glow, bathed in an aura of sinister chakra that significantly enhances its cutting power, as well as the weight behind its strikes; a property which also extends to any kenjutsu or kenjutsu-based shape transformation techniques performed with it. However, even with Yousei's current level of affinity, the constant drain that the blade places on her chakra reserves makes prolonged use exhausting and overall inadvisable.
(Attaining greater proficiency with Kenjutsu and Shape Transformation will further increase Yousei's compatibility with Yosuzume, allowing her to bring out the cursed sword's true power.)
Shape Transformation [Journeyman]: A cornerstone of many traditional samurai techniques, Yousei is quite skilled with the art of applying shape transformation to raw chakra. While she primarily utilizes this proficiency in conjunction with her kenjutsu, lately she's also begun exploring several other potential avenues for its application, including one technique in particular that she's been working on perfecting.
Updating the description of Yousei's Shape Transformation again, to reflect the recent change of Barrier Ninjutsu being incorporated into the proficiency.

Yousei also has a particular aptitude for the creation of barriers; most commonly in the form of rapid defensive wards, though she can also produce barriers with slightly more complex effects like detection, albeit on a smaller scale for the time being.
