It's
the rule that whenever we see two hot men in fiction interact with one another, regardless of how silly it may appear, people
will ship them.
The Spanish Armada introduced the Dreadnaught class of ships in order to overpower the smaller British ships with it's large size and firepower. They got their asses handed to them by the Brits' smaller ships.
On the actual topic on hand: Persona 3 MC and Yukari always perplexed me since the game push her to be the semi-canonical love interest. But her bossy personality in the main game and her attitude in The Answer were huge turn offs for me. Hell, I never bothered to complete her social link since it's gets reversed so easily.
I ship Yukari x MC more than Aigis x MC. At least she's a human being, lol, I just don't understand non-human x human shipping in any sort of media, it's just weird most of the time.
Also I thought the Answer handled her marvelously. Her motives were selfish, yesh, but it was understandable, especially considering her circumstances in the main game. The way the game handled her arc to the end where she can finally accept the MC's fate was really good.
