Nnoitra x Tesla is another of my OTPs, even if I wouldn't say it has as many hints as IkkaYumi. That of course is because they're not in the manga as much.

Why the comparsion was relevant to me was because I wanted to show that even if we have hints for other couples, IkkaYumi stands out in this matter. But having so many comments on that part... I'll take it down ;)
