[M4A] Playing female to introduce one of two characters, medieval fantasy with magic OR Re:Zero fandom

My writing style tends to be on the shorter side with images and GIFs as I believe strongly in "Show, don't tell.". Some of my paragraphs are vaster of course. I try my best to make it interesting and creatively chaotic, not linear and planned out from the start. We can discuss how you'd like to approach my character on discord only as well as expand on character descriptions and some world building.

Sister Lyra
One of the characters I'd like to play is the mysterious Sister Lyra. Seemingly a priestess who spreads the merciful goddess Lumina's guidance and resides withing the temple to lumina in a moderately large town (will check the name if I've already named it). Her appearance and actions are, however, unusual. She wears no cross on her neck. She never shows more than her face and limbs as her temple robe is always hooded. I have some world building set for her world already.

Lilishka Rosaline
The other character is the ancient vampire progenitor Lilishka Rosaline, also known as Lily, Lilith, the Lady of Roses and the Great Destroyer. Her pale skin is clothed in a black dress adorned with dark red ornamental roses atop black petal bases. The same roses and petals that paint her attire as ornaments on her head and neck. She roams the lands during the day holding her black parasol to shield herself from the sun, which doesn't affect her as badly as most vampires. Lily has a strong sense of justice and a fine taste for art and honey wine. She has mastered shadow magics over the millenia and developed unnatural strength, swiftness and regenerative ability. Honey wine, divine magic and equipment, as well as prolonged exposure to the Sun, that is a deadly laser (reference) are the few weaknesses she has.

Re:Zero
Other than original scenarios, I'd also like to play as Lilishka Rosaline in a roleplay that takes place after the events of the prequel movie and Season 1 of Re:Zero where she would cause Subaru's return ability. You would play as Subaru and take different paths learning more and more, but never being able to tell anyone about your past lives as the witch's curse would stop you and your weird subtle moves allowed by it would be questioned and suspected by my character and the characters in Season 1 of the anime, etc.
