When the clan succumbed to chaos and became a Blob Phantom, Kazuma had asked Yato to kill them to save Bishamon. This is the reason Kazuma is indebted to Yato and why Bishamon hates him. Kugaha plans to become Kazuma's successor after killing Bishamon and reincarnating her. Yato and Yukine fight Bishamon, mistakenly believing she kidnapped Hiyori. When Bishamon proceeds to kill Yato, Yukine jumps in front to protect him, being cleaved in half.
