PLEASE

Vampire princess has her inner demon summoned along with her fathers and they find out some of the actual feelings - princess felt like she was a bird caught in a cage while the father didn't want to hand her over to the mc. Twin dragons show up as transfer students one male one female, mc finds out that the male was a female however she thought she had to act as a man to be the heir. They actually show up to the school to challenge a dungeon, get their asses beaten, mc and friends show up and find all of that out. They give the dragon twins their assistance to challenge the dungeon, turns out beat the dungeon you needed to have a large group - dungeon boss is a pheonix who wanted a strong fight and it's only the dragon twins fighting it. Two chapters go by and they're almost defeated and then mc goes all koolaid man and busts open a wall to fight the phoenix. That's the end of the volume.

Sorry for the terrible explanation but it covers most of the content.

thank you ! that was an excellent explanation!
