Chachan has had a trinket he's carried with him since his creation - his cactaur earring.
As has oft been alluded to in RP and other things, it's a memento left by his brother before leaving to pursue his own dreams. Due to the lack of contact - and the razing of Doma - it is effectively the only thing he has left to remind him of his older brother. Whenever he talks about his brother, or even thinks about Gogonji, he tends to fiddle and play with it unconsciously. He's also rather protective of it, for obvious reasons.
Gogonji, of course, maintains the other half of the pair - but it's more of a morbid keepsake. After all, he believes his family is dead, so the earring is all that he has left of them beyond his memories. He's still just as protective of it - if not moreso.
