The Mysterious Obstacle is a student that's apparently Osana's best friend. She's unable to be killed and follows Osana everywhere. She's supposed to make killing Osana much harder than it's supposed to be.

We also have a lot of evidence to prove that she's Rival-chan. When she was added ingame via mods, she used hairstyle 21 (used to be Rival-Chan's hairstyle). Since said heirstyle was deleted, she appeared completely black when added ingame. Additionally, her strangth is "Indestructible", which alludes to Yandere Dev's video eries called "Indestructible Rival", which was about Rival-chan unable to be killed.

Lastly, we can believe that she's the former leader of the Martial Arts club. Yandere Dev says her story wouldn't work out if she was anything below a Senior (because you need to be a Senior to be a club leader). She, Itachi, and Budo are the strongest students at school. Along with the fact that the former Martial Arts Club leader was confirmed to be a girl (and left the club), and the Mysterious Obstacle is the strongest female, we can assume that she's: I hope this cleared things up for you.
 * Rival-chan
 * Former leader of the Martial Arts Club
 * Budo's love interest
 * Literally unable to be killed
 * Not going to be added until Osana is because her routine revolves around following Osana
