|Role||Rival (Teacher of Class 3-2)|
Mida has dark brown hair tied up in a ponytail and brown eyes. She has a beauty mark on the bottom left side of her face and red lipstick. She wears a tight black suit jacket with a red bra slightly showing. She also wears a tight, short, scarlet skirt, black thigh-length stockings with a black garter belt attached, and red heels.
"Mida is a substitute teacher who absolutely loves her job; there is nothing that she enjoys more than having dozens of eyes all directed towards her...especially if those eyesbelong to teenage boys.
Mida will appear at school in the seventh week of gameplay in order to fill in for Kaho Kanon. She will quickly begin hunting for new "prey", and Senpai will catch her attention.
Her hobby is seducing schoolboys, and so far, no man has ever been able to resist her charms. If she decides that she wants someone, they have no hope of escape. Senpai won't be able to escape her clutches unless someone takes drastic measures..."
Mida's default reputation is +10
Though it is unknown at the moment, YandereDev has said that her routine will put her in close proximity to Senpai or other students.It is presumed it will be the same as a regular teacher. In the future, she can be called upon by Teacher's Pets if they witness a murder.
The topics towards Mida Rana are (Negative/Positive/Neutral) as follows:
- Everything else.
- Main Article: Senpai
As she is a rival in the future, she will have a crush on Senpai. She goes after him because she is finally ready to "settle down".
Senpai entering a relationship with Mida would be very complicated. He would eventually get a job in an academic institution.
- Main Article: Suitors
- YandereDev states that she may be the tallest rival.
- Since she is a sub, if she is eliminated peacefully, she will disappear after her week is over.
- Her name is derived from "Midara" (みだら or 淫ら) which translates to "indecent", "lustful", and "Sluts". "な" (na) is an adjective-modifier. It could also be from "midarana" (みだらな) meaning "lewd".
- YandereDev has stated that Mida would likely leave a note for Senpai, put on a comically under-sized schoolgirl uniform and confess in an exaggerated "schoolgirl confessing to her Senpai" act.
- Like Muja Kina, she won't have a reputation stat, but will instead have a 'job performance' stat, which will be lowered in ways other than gossip. When this drops significantly, she will be fired.
- YandereDev does not believe she is acquainted with Muja Kina.
- Mida Rana was inspired by Noriko Kashiwagi from Persona 4 and Mitsuka Yoshimine from DearS. 
- Mida has tried to seduce boys 69 times.
- Mida's mother would probably be similar to her in appearance.
- Mida wouldn't react negatively if she sees Ayano taking panty shots of her, unlike most NPCs. She will also not expel/apprehend/report the player for that matter.

You really should be a bit more discreet about that sort of thing, darling. / You'd better be careful, dear... that's dangerous territory for a young woman. / Here's some advice, sweetie... next time, make sure that nobody is watching. / Goodness! You're bound to get into trouble if you keep that up, honey... / Tsk, tsk! You'll never learn unless you're punished for your mistakes. Come with me, sugar... we're taking a trip to the Guidance Counselor.||”|
