It looks like Akihito will be sacrificed. Or so it seems. Apparently, his youmu half is the strongest youmu of them all. Which makes me suspicious. The note that Hiroomi saw said that it was believed that Akihito held the Kyoukai no Kanata. Does that mean that someone put that youmu inside of him? Maybe his youmu half isn’t really inherited from his father? Maybe someone thought it would be a good idea to seal the most powerful youmu inside him (*cough* Naruto).
Anyway, the preview seems to indicate that Akihito died in the fight against Mirai. He’ll likely come back (which irks me), but I wonder what happens now. I guess everyone tries to figure out why exactly the Spirit Hunter Association organized his death in the first place? Although, is that really a question? Why wouldn’t they want to destroy the most powerful youmu, who could bring ruin to humanity?
