If I’m not wrong, Haya Susanoo wo no Mikoto is referring to the Shinto god Susanoo, right? So Ena’s grandfather is a Shinto god? .________________.
If so, the Ama no Murakumo no Tsurugi that Ena holds is probably the Kusanagi no Tsurugi that Susanoo obtained while slaying the Yamata no Orochi (in fact, “Ama no Murakumo no Tsurugi” is the other name for the Kusanagi no Tsurugi).
Color me interested, I’m now curious about Ena’s abilities.
