Hikaru Asahina (朝日奈 光, Asahina Hikaru) is the fourth son of the Asahina family.


He wears a blue shirt covered up with a brown jacket and a blue, cheetah print scarf. He also wears blue jeans with lighter blue, cheetah print pockets.


Hikaru likes watching his older brothers' reactions around Ema.

He is very cunning, being able to provoke reactions from his brothers with only a few simple questions. He has a very sly nature, similar to that of a fox, and is able to get what he wants through harmless manipulation so. He also has something of a slight sadistic shade to him as well, seeing the conflict of his family as a game and keeping statistical track of each brothers' chances, including his own. This is further emphasized in season 2 volume 2 (Ch. 27) when he suggests that they all start forcing themselves on Ema and stop being so tame, which earns him a punch from Kaname.

Still, in the end, he is a good person who cares about his family, albeit in an unorthodox manner.


Hinata EmaEdit

Hikaru is possibly the only brother who's feelings for Ema are not romantic, though he claims that he will participate in the next "round" of the game. They remain on friendly terms, and Hikaru has shown a protective side to himself when he uses blackmail to make Fuuto leave Ema alone during the Christmas Special. He also shows a perverted side when, in the same special, he gets in the bath with Ema; he doesn't do anything besides moving closer, but it is still a pervert move on his part since they were both naked.

Asahina UkyoEdit

He seems to be on close terms with Ukyo. It is seen that he always teases Ukyo when it comes to Ema.
