*SPOILERS FOR THE ENTIRE SERIES and possibly word of God aka Kubo-sensei’s interviews/tweets/etc.*
This is by no means an extensive post on every instance I’ve found evidence that Vik is ENFJ, but these are the things that stood out to me when I was trying to type him. I did originally peg him as an ESFJ, but this man does not have Si lol.
Also Vik is definitely not ENFP (I dedicate this statement to my friend Yao, who would be happy to see me tell y’all once and for all) and I will show you why…
Fe – Vik asks Yuuri what role he wants Viktor to be in their relationship. He’s picks up on Yuuri’s feelings easily (though, he’s not always accurate) and, as Yuuri said, meets him half way. Viktor’s go-to action was to try to adapt his role/persona to Yuuri’s needs (Fe) vs. Yuuri’s request for him to just be himself (Fi).
He urges Yuuri to be nicer to his fans and expresses disappointment when Yuuri is all into his own internal issues (Yuuri has Fi btw, which is a good contrast here).
Also, see the season 1 finale where he hides his true feelings for Yuuri’s sake at the Kiss n Cry when he says he’s coming back to skating. We obviously know he’s shook because he doesn’t want Yuuri to retire, but he doesn’t say anything to tip Yuuri off because of Yuuri’s excitement/happiness that Vik is coming back to skating.
He rarely loses his temper, and even when he does he doesn’t lash out. Vik is also pretty expressive facially – which isn’t giving much insight on his Fe itself. Usually Fe users tend to be more expressive with their faces and Fi users show emotion more with their eyes. That’s just a fun thing I noted. (insert HEART MOUTH SMILE).
Ni – Even though Vik was lacking two the L words (love and life) for years during his skating career, he can still get the “feel” of what he needs to present to the audience in order to perform his routines. He also has a hard time describing in words what “agape” means to him – he imagines it in a more abstract way than concrete, so it’s more of an idea than something tangible.
Se – Viktor has impulsive spending habits (like me!). He’s got an eye for things that are aesthetically pleasing. He also suggests to burn the tie Yuuri wears on television. In addition, when Yuuri is trying to find his eros and says that katsudon will be his source of eros, Viktor goes out to drink and arrives back in the morning with a hang over. Viktor also picks up on Yuuri’s non-verbal behavior in the (PROPOSAL) episode and also that Yuuri was his fan from the way Yuuri skates.
Ti – Vik can be pretty critical – he’s quick to point out what isn’t working and we do hear his internal logic in the narration that gives us some insight to his thought process.
