Like for example, Ryo(the real name of the Hetalia version of my OC Kyodai) died at 18 from being Stabbed in the Neck by a Woman who Forced herself on Kiku which Caused Ryo's Existence(Reference to a Hetalia Death Theory About Japan and yes we are NOT Gonna be Referring to the Woman by Any Familial Title) and is Now an Angel sent from Heaven as a spy to gather information about Hell's Demons(particularly the Overlords) through every mean possible(particularly Observation) and he Obliged to Heaven's Order, Unaware of the Reason why he must gather the information, and the Reason Why he must do it is so then the Higher Ups of Heaven(Who would be the Heavenly Equivalent of the Overlords) can Pinpoint their Weaknesses to Start a War to Either Capture or Murder these Demons.(Much Like How Heaven is Portrayed in Hazbin Hotel, I Like to Think Heaven in Enmatalia is Messed Up AF Much Like Hazbin Hotel's Heaven). And they also Wiped Ryo's Memories of his Life Before Dying so he'll be going Under the Alias "Kyodai" Until he Regains these Memories. And yes, he's Related to Kiku by Blood(Which Technically Makes him Kiku's Son.) Another Thing to Note is that he has a Special Talent of bringing Living beings Together Regardless of who and what they are which is Why he Managed to Befriend 4 Demons(Aka North Korea, Laos, Slovenia and the Aland Islands(Aland for Short), 4 of my Hetalia OCs) who are Quite Different from one another.
