For me it was:
• Dash x Dot from Kimba the White Lion
• Jack Savage x Skye from Zootopia
So what about you?
The ship Mikayuu (MikealaxYuichirou) got me into the entire Owari no Seraph or Seraph of the End fandom.
Kamijirou from My Hero Academia
Hm, I have a few ships like this.
As @I'mRunningOutOfUsernames MikaYuu got me to watch Owari no Seraph.
Nygmobblepot (Oswald x Edward) kinda got me to watch Gotham, but it was one of the reasons I started this show.
Hannigram (Hannibal x Will) was one of the reasons I started watching Hannibal too.
Yeah, I think that's all, but I might be wrong.
I think it was MomoJirou or ShinKami that got me into My Hero Academia.
What do you think?
