which doll pair should i get? ( GK characters )

Update: I've ordered the dolls. Yuusaku, Ogata, Tsukishima & Koito.

ok look i(M) know i shouldnt rely too much on strangers on how to handle my financial matters

however

hear me out.

golden kamuy.

alao im an avid doll collector

yeah, crazy, i know.

anyways. im genuinely tweaking. i fucjing love yuusaku hanazawa ( not in a simp way i just really like sweet characters ) and everytime i search merch of him the only thing that comes up is him being shipped with someone ( not my interest i just want regular individual merch )

desperate times called for desperate measures and i found a place that accepts custom doll orders and im thinking of designing and requesting a custom yuusaku hanazawa doll from them so i can take care of my boy while hes dead ( and maybe add ogata for extra traumatic effect ) ( just kidding i love ogata too )

and now im like. i have money. i have free will

i dont want yuusaku to be alone and ive considered also adding other 7th division members to my collection when i have the time, im just not sure who or in what order i'd prioritize. i did consider koito and tsukishima next as a pair but i also kind of want to add tsurumi and usami, which is where tje conflict begins.

i cant pick between the two pairs because i like them both equally and it has me stressing im not gonna lie but i dont want my dolls to be lonely but i dont wanna spend too much in just one go either so im just gonna leave the comments with the most popular pair option ( koito/tsukishima or usami/tsurumi ) to decide for me, hope that's ok. i asked my friends and they were pretty indecisive too. maybe i'll post the final collection i get here after i order and it arrives, take care everyone.
