With all due respect to Fujoshi and Fundashi with fetishes that can never change, but not all Seme need to be big shouldered with big muscles and even bigger voices. They don't have to be stern or angry or overtly pushy. I know Iason Mink is not all of these things. I'll leave him out of the mix for this argument, so more of you may listen to what I am proposing. More and more mangaka and novelists are realizing this and crafting characters that are so complex and subtle that it is hard to spot the Seme in the room. Conversely, the uke are no longer all timid and quivering. This is very refreshing, and to me a far more interesting read. Who wants to read what is the same story over and over again? It also never made sense to me why such strong and uncompromising characters would be interested in the timid and weak willed. This sort of attraction always smacked of Seme that aren't really the incredible lovers they were purported to be. One might argue – and more than one has – that these Seme are being protective. If that is the case, what IS up with the raping and over all physical abuse? That's real protective. And it's real manly of someone who is often twice as big as the uke. And no, that horse will never be too dead for me to stop beating.
Where was I? Ah, yes. With all these changes, how do you spot the Seme in a manga or anime? It's still easy enough. It's all in the personality. A Seme is a catalyst for significant action in a story. He's doing stuff, and usually that stuff is ahead of the curb of everyone else. He has irresistible charisma or force of personality that gets even the hesitant to do his bidding. That is NOT the same as being able to bully someone into obeying. This is the ability to make what they want to do so compelling that everyone – not just the uke – feels they must to it. They are self possessed in general. This can manifest itself in a couple of ways. Either the Seme is supremely confident of their personal abilities or they know what they want from life. Sometimes, it's both. The main thing is that the Seme brings order to a uke's life as well as love. Sometimes that is actual protection in some fashion and other times it's personal fulfillment. To bring this kind of order, a Seme MUST have control of himself as a person. Also, a Seme doesn't have to be the one always pitching sexually. He's brave enough to know what he wants and have it.
And it's time to play 'Whose Your Seme?' Some of these shows are yaoi, some of them have tons of shipping or fans creating doujinshi. Let's begin with fans Starfighter webcomic. Everyone and her uncle thinks that Cain is the Seme because of his rambunctious greeting of Abel early in the story. He certainly seemed to be have his way with Abel whenever he felt like it. But Cain does not have enough self-possession to be a Seme. He can barely keep himself in check enough to keep from fighting his fellow gunners at the drop of a hat. Meanwhile, since their first mission together, it's becoming more and more clear which one of this pair has more self control and more control over the relationship. Abel kept Cain from starting a fight with some snots that really needed a punch in the face and then there is this line during the last mission: I'm not going to let them hurt you. Given what they were facing, that's a pretty badassed Seme line to me!
Finally, I think these changes to Seme are wonderful, because it has caused the rise of the Dangerous uke. The uke of Tightrope and Ikoku Irokoi Romantan and Tyrant Who Fall in Love could not have existed if these tropes had not changed. That kind of change is truly a beautiful thing. Observe:
