Synopsis by Jason Buchanan
Sibling rivalry between two half-brothers comes to a head when love is put before family loyalty in this anime adapted from Kazuma Kodaka's popular romantic manga. Kei has always been leery of his unpredictable half-brother Kai, but when Kai appears out of nowhere to seduce his brother's one true love Ranmaru Kei's passive suspicion quickly gives way to unbridled rage. When a mysterious figure from Kai's past makes a surprise appearance, the unforeseen development threatens to tear the already dysfunctional family apart.
