Eirin Yagokoro

Summary
Eirin Yagokoro (八意 永琳) is a medical genius from the Moon, able to create even the Hourai Elixir with the help of Kaguya'spower, the manipulation of eternity. She is living in exile in Gensokyo after choosing to stay with and devote herself to Kaguya Houraisan on Earth rather than take her back to the Moon. She was a very well-known figure on the Moon, having not only been instrumental in the founding of Lunar society with Lord Tsukuyomi, but also being its leading medical mind and the person in charge of the Moon's emissaries to the Earth.

<p style="font-weight:normal;font-size:14px;">Intelligence: Extremely high - Eirin is a genius, far smarter than even the likes of her family, a distinguished and highly influential line of medical geniuses. She is supposedly capable of using her immense knowledge to create any sort of drug or medicine, and she has extensive knowledge on historical events, particularly those involving the Lunar Capital. She is likely to be the smartest being from the Moon, who compared her knowledge to Omniscience despite seeing inventions such as immortality elixirs and Planck bombs as outdated technology. She was not only instrumental in the founding of Lunarian Society alongside Lord Tsukuyomi, but she was also its leading medical mind, and was in charge of the Moon's emissaries to Earth.

<p style="font-weight:normal;font-size:14px;">Weaknesses: None notable.

<p style="font-weight:normal;font-size:14px;">Notable Attacks/Techniques:
 * Making any drug: Eirin's medical expertise allows her to create all sorts of drugs and medicine, from ordinary medication for common colds, to drugs capable of manipulating one's dreams and life. She still needs the ingredients necessary to make specific drugs, and cannot make anything that would be physically impossible to make. Among the many drugs she made is the Hourai Elixir, though she required Kaguya's assistance.

<span class="mw-headline" id="Spell_Cards" style="font-weight:bold;">Spell Cards Edit

 * Esoterica "Astronomical Entombing": Eirin tampers with space with no reason.
 * God Sign "Genealogy of the Sky-Born": Lasers that resemble a genealogical tree.
 * Medicine Sign "Galaxy in a Pot": Even more exaggerated than Earth. It's still in a pot though. It is suggested that this spell would easily create a black hole.
