Player name: ara
Character name: chiyo
Visibility/memorability: yes, to the retrospec effect! how often yato hangs out at the flower shop, etc, i guess will affect how soon chiyo's memories of him will fade unless there are other places she'll see him more?
Yato's stalking: if yato would stalk chiyo, have at it
Yato’s home invasion: same as above!
Anything else?: honestly, i hope chiyo finds out his influence on yukine and mafuyu, and that memory comes and goes to both their benefit and detriment. also, if yato ever invokes the i'll grant your wish for 5 yen and advertises it like he does in canon, chiyo will feel so terrible for not remembering him all the time that she'd probably start exchanging/saving 5 yen coins (or nickels) for him
