I'd suggest checking manga forums or dedicated Bleach fan sites. They often have detailed breakdowns and recommendations on where to pick up after a specific part. Sometimes, the author or official sources might provide cues as well.
Honestly, I don't know when the TYBW manga starts. But you could search manga databases or ask in manga enthusiast communities to get the details you need.
Another element is the stigma. In society, there are still people who look down on special ed students. This negative attitude can be reflected in the school environment. For instance, special ed students may be isolated from other students, which is a form of 'horror' for them as they are deprived of a normal social environment.
One aspect that could make them special is the author's unique perspective. Maybe Grabianowski has a way of looking at horror that's different from others. For example, he might focus on the subtleties of fear rather than just the big, obvious scares.
Another important ability of Rukia is her high - level of spiritual pressure control. This allows her to sense the presence of other spiritual beings, and also helps her in combat situations to better manage her energy and attacks.
