Protect A God or Die Trying?! Odin, the chief deity of the Norse pantheon, has come to visit Japan on important business, and Issei and the gang are tasked with keeping him safe. Guarding a lecherous old fart of a god is tough enough on its own, but to make matters worse, Akenos estranged fallen-angel father has also been asked to protect Odin. As Issei searches for a way to help the two reconcile, disaster strikes in the form of Loki, another Norse god, who isnt too happy about how Odins been running things. Its been said that the Red Dragon Emperor has the power to best deities, but will that truly be enough this time? Our hapless hero may need some help from the most unlikely source...
