Ruan Mei

Jump to: Materials | Skills | Traces | Eidolons

“A member of the Genius Society and an expert in life sciences. She teamed up with Herta and others to develop the Simulated Universe.”

“Want some pastry? The plums used in this recipe are freshly macerated, and I waited in line a long time for them.”

“A sweet-tempered and elegant scholar. Member #81 of the Genius Society. An expert in the biological sciences.

She earned Nous' attention with her talent and terrifying perseverance, and began her research on the origin of life in a secret corner of the universe.

For that, she was invited by Herta to collaborate with Screwllum and Stephen to develop the Simulated Universe.

Secretly, she greatly enjoys traditional theater and desserts, and she is also very interested in embroidery.”

Ruan Mei is a 5-star Ice character on the Path of Harmony. Her Skill can increase the SPD and Weakness Break Efficiency of all of her allies while her Ultimate can buff All-Type RES PEN and inflict a unique debuff. Her Talent is straightforward – buffing her allies' DMG passively and dealing more damage against Weakness Broken enemies.

Ruan Mei will be fresh in the minds of many as she's a prominent character in the Simulated Universe in many forms. She often talks through her avatar, similar to how her fellow Genius Society members and Simulated Universe developers Screwllum and Herta.

Ruan Mei Signature Light Cone – Past Self in Mirror

She once loved to seal the moment when plum blossoms are on the verge of wilting and keep it close to her.

It has been many years since then. Many lifeforms — rambunctious, sweet, and everything in between — have bloomed from her hands, but the plum blossoms still wilt at their preordained times.

It has been many years since then, and the face within the mirror still looks the same. However, on the scale of the entire cosmos, would she also only manage to keep her freshness for a fleeting moment?

“If everything is doomed to die, what would be the purpose of creation?”

After a silence that seems to stretch to eternity, the winds blow the flowers to the ground, and the reply from the person in the mirror is the same as always.

“For the day when we no longer keep the plum blossom.”

She caresses the icy surface of the mirror. Such soliloquies had happened too many times for her to count.

Increases the wearer's Break Effect by 60/70/80/90/100%. When the wearer uses their Ultimate, increases all allies' DMG by 24/28/32/36/40%, lasting for 3 turn(s). Should the wearer's Break Effect exceed or equal 150%, 1 Skill Point will be recovered. At the start of each wave, all allies regenerate 10/13/15/18/20 Energy immediately. Effects of the same type cannot stack.
