They aren't an official couple, but they share so many personal moments that it's hard not to envision a love story behind the scenes! Other bromance couples in Seraph of the End include Guren and Shinya, but Mika and Yuu are absolutely suited for each other, which is why we selected them. Mika is one of the main characters in Seraph of the End who's in love with Yuu. However, since they're from different worlds, they can't ever meet or even talk to each other until about a year has passed. Even then, they don't really get a chance to develop their relationship because most of their time is spent fighting off enemies that attack them both. Despite not being an official pair, they do share so many personal moments that it's hard not to imagine a love story behind the scenes! In the manga version, they actually do end up meeting and developing their relationship over time. But in the anime adaptation, they jump right into romance without any background information. Although this might make sense since Yuu starts out as a villain who turns good at the end of the series, it doesn't change the fact that Mika suffers as a result of their relationships not having any background development. If the anime were to adapt the manga version, this would allow for more room to explore their relationship.
