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.
Some of the Bleach captains could potentially ally with the angels. Considering their own sense of justice and the fact that they fight against evil in their own world, they might find common ground with the angels in the Highschool DxD setting. This alliance could be based on mutual protection and the goal of maintaining peace in the supernatural realm.
Well, the Bleach captains' abilities are quite powerful. For example, Hitsugaya's ice-based zanpakuto could be used in interesting ways in the DxD world. It could freeze demons in their tracks. Their spiritual pressure might also have a significant impact on the supernaturals in DxD. They could potentially intimidate lower - level devils or fallen angels just with their presence.
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.
