Yozakura Quartet, Volume 29 (Yozakura Quartet #164-167)

Preparations continue for the final battle against Akina's ancestor and god of death, Oushuu Hiizumi. In order to strengthen their inner divinity, a requisite for going toe-to-toe with the almighty, the gang holds a training camp at the Senate's onsite test facility, using state-of-the-art weaponry that is the culmination of decades' worth of research. But in the middle of their session, a virtual interloper appears as a glitch in the system - one Akina and co. know all too well!
