Name: Rumi (K-Pop Demon Hunters – Pokémon Universe Version) Age: Ageless (Half-Shade, Immortal) Affiliation: Assistant to Professor Nico Robin, Member of the Main Pokémon Team Partner Pokémon: Mimikyu (primary partner)

Personality:

Highly intelligent, calm, and strategic; the “older sister” figure to the younger main cast.
Protective and nurturing toward allies, especially the younger trainers in the group.
Maintains a mysterious aura due to her half-shade origins, but has a soft, gentle side that comes out in trusted company.
Can be quietly playful with Mimikyu and close friends.
In battles, she becomes intensely focused, reading opponents like an open book and striking decisively.

Background: In this universe, Rumi travels alongside Professor Nico Robin as one of her most trusted assistants. Her duties involve researching rare Pokémon, safeguarding the professor’s field expeditions, and mentoring the younger main team members. Rumi’s unique abilities as a half-shade give her enhanced senses and almost supernatural reaction time in battle. She forges strong bonds quickly with those who prove themselves loyal, and she treats Pokémon with deep respect and empathy.

She shares a particularly strong bond with her partner Pokémon, Mimikyu, whom she rescued as a neglected wild Pokémon. Mimikyu is fiercely loyal to her, often perching at her side or hiding in her shadow between battles.

Relationships:

Professor Nico Robin: Mentor and close ally; trusts Rumi completely in research and protection.
My Main Cast (Sora Kashiwagi,Umaru Doma, Maple, Sally, Tohru Honda, Shizuka Yoshimoto, Hina Tsurugi, Kyo Sohma, Iruma Suzuki, Yuuichi Katagiri, Kei Shinomiya): Rumi is the steady and reliable older sister figure, often guiding them through both travel hardships and gym battles.

Battle Style:

Prefers a balanced approach of strategic offense and flexible defense.
Utilizes type advantages creatively, often setting up battlefield conditions that favor her team.
Works in sync with Mimikyu to set traps or force opponents into making mistakes.
