The story is a tragedy, even if the heroes win it'll end with a bittersweet ending. It'd be interesting to see one of the Vampire Progenitors sacrificing but the main issue here is that the interactions, bonds with humans never developed; they developed a bond between themselves but not with the main characters. Which is highly discarted but you're not so far when it comes to the second person.

Indeed Yoichi and Kimizuki wouldn't sacrifice their lives because they've suffered enough, they're walking a path on which is close to the famous taboo; Guren is by default a character that will die to give humanity the strength to fight back the real enemy for the World. After all, he is on his limit.

Yu will be the first to leave, he's going to leave a bitter feeling for those who were around him, but since he's kind, he'll likely give a second chance to those who suffered enough, including Mika.

Yu is selfless, he worries about his family, he worries about them to no end and wants to see them alive and healthy, he doesn't want them to danger themselves.

But I discard Mika for a sacrifice for humanity he would likely keep Yu safe instead allowing him to go down a path of no return
