Character[]
A girl from the Celestial race. She has long wavy black hair and big breasts. While traveling in a horse-drawn carriage to visit a merchant who was an investor in the orphanage, she was attacked by bandits and fell off a cliff, causing her to regain his memories of his previous life. After that, she no longer goes back to the orphanage or the merchant, but instead decides to build a house in the forest and live there. She can use creation magic and can create matter from nothing. However, since using creation magic requires a large amount of MP, I try to manufacture things whose structure I understand by preparing materials and using magic.
She also has the legendary skill of storage, which allows her to store matter in phase space and eject only desired objects. While she enriches his life by growing vegetables and hunting, his intellectual curiosity has turned to sexual interest due to his body being of a different gender than in his previous life, so she is also focusing on developing sex toys. In his previous life, she was a man in his 30s named Renjuro Yuuki, and she was a researcher working for a manufacturer.

Abilities[]
Ren's magical talent and the scientific knowledge of their previous life are very useful when applied in combat, giving example her Air barrel applies a physical acceleration of wind magic it stimulates through his 「Creation Magic」 by throwing a pebble or a dagger in high speed. Her 「Creation Magic」 needs specific requirements like material and vision on what she wants to build or come up with. Every item she created costs to minimum of 10 mp to 300 ⬆⬆ or much higher depending on the construct of the item she revised. Her [Creation Magic] can do just about anything she wants, provided she can supply sufficient mana.

[AGI] | 4 | [MGC] | 390 | [CHA] | 24 | [LUK] | 4 |
After becoming a Celestial, her INT is 500, her MGC is 300, and the only other base stat that is not in the single digits is CHA at 14, once she was able to get proper nourishment. The power of a pistol or a rifle is an average bullet velocity of 200 m/s = cost 1mp ➧ 400 m/s = cost 5 mp ➧ 800 m/s = cost 20mp and so on, she applies this method for combat. Her aim assists by the skill of 「Snipping」 and 「Hawk Eye」 for long-range attacks giving her more advantage in combat in this style of fighting.
She cares only about her interests. If those interests happen to align with yours, congratulations, you've just gained a powerful ally. For example: a dangerous monster terrorizing the trade caravans? Meh, let someone else deal with it. Dangerous monster happens to be a giant bull? OOH! I want a nice steak dinner! so her actions manifest new skills simply by existing. Waking up in the forest, after a horrible night, due to a broken ankle caused by the carriage crash has her manifest [Tolerance: Fatigue], [Tolerance: Pain], and [Tolerance: Hungry].

It is deconstructed and reconstructed. Multi-tasking in the lab led to an explosion for the 30+ researchers that killed him. Once awakening these memories, Ren soon develops a multi-processing skill that allows her to focus on up to four tasks simultaneously. This allows her to fashion a well-camouflaged, golem-propelled carriage that she can drive in her sleep! Despite having no problems with her vision, she crafts a pair of glasses with [Appraisal Level 2] to hide the fact that she has [Appraisal] as an inherent skill, so she's not turned over to a certain toad-faced merchant.
By the time chapter 110 comes around, she's the only blacksmith in the kingdom who can work with adamantite, forging a sword that can rival the equipment normally found in dungeons, which are considered trials placed by god! Although Vector did keep his word to keep the origin of said sword secret, word of her skill somehow made it to shady individuals who tried to have her kidnapped to force her to work on their behalf.
in, up to and including building a freaking Gundam! But once the shock wears off and she feels safe again, she leaves it all behind, including sneaking away from a sleeping Alyssa and Lily to go pick bamboo shoots alone in the forest. Lily and Alyssa tear her a new one for that, lecturing her for hours, while Norn pins her to the ground with her forepaw to make her reflect on her actions.
