Just for my own tracking (and because it seems so trendy~)
Pings
Angel: Called "Angel" by Iris
here. Feels important, but he's not quite sure how.
chosen(word): Chosen referring to himself as such. Evoked a feeling of nostalgia and duty.
Hunny: The usage of this word by Chosen makes Seraph want to facepalm.
Goddess: The Goddess mentioned by Archangel
here. Causes him to remember the "Goddess" he slayed in his own dream. Curious about any connection. Feels remorseful at trying to remember it.
Sword tech: Sword technique performed
here. (Demon fang). Feels natural to him. Unsure of how it was done.
Wings: the wings described by Chosen
here. Rings a bell.
Cruxis: Name of... something mentioned by Chosen in his journal
here. Rings MAJOR bells.
Archangel(person): Everything about this man rings warning bells. Both good and bad. He finds Archangel's philosophy different, though has slight disagreements.
His Son: From his first memory
here. Seen as a young toddler. Seraph longs to find him.
Slightly More abstract
His humanity: Does not sleep or eat. Other Spherians seem to think this strange. Trust and Baretta have asked what he is in his second journal, sparking a curiosity.
His Humanity, part two: In Archangel's first journal, Archangel mentions that those who do not require basic human needs cannot be human. Seraph believes they are the same kind of creature.
Cruxis Crystal: Unaware of the purpose of the softly glowing, blue stone embedded in his left hand. Feels no need to trouble others about it, as he sees none of the gems on anyone else.
Relationships
Chosen(person) The redhead feels familiar- very, very familiar, yet Seraph still feels the need to slap him. Resists this urge. Currently roommates. The longer Seraph hangs around him, the more he grows to respect the redhead.
