Wataru Asahina (朝日奈 弥, Asahina Wataru) is the thirteenth and youngest son of the Asahina Family.
Wataru has short, light salmon-colored hair (with a single hair standing above) and brown eyes. He wears a yellow long-sleeved jacket-like, with 7 buttons, that the color of the inside is pink, allowing to see another white long-sleeve inside. He also wears a pair of short shorts, that has laces at the end. Wataru has yellow-colored shoes and the top view color is red. He also has a rabbit toy in the jacket's pocket, similar the one Masaomi gave and a big cat necklace, and has a watch attached on his left hand. Being the youngest, he is also the shortest among the Asahina Brothers.
In season 2, he appeared to be taller, as he gained 10 centimeters (150cm now). His hair is much thicker, and seen to have a little ponytail in the left side, with a teddy bear as its cover. Wataru now wears the Bright Centrair Uniform; a white coat that has a cross-shaped symbol at the below the collar, with a blue with gold-striped ribbon sticking on it. From the inside, he wears a vest that has 5 buttons, and a polo under it. His short shorts in season 1 changed too, as he wears a striped pants, with a pink, fluffy and tamagotchi-like toy near his pocket. The yellow-colored shoes before habe changed into a pair of big brown boot-like shoes. However, Wataru still has the rabbit toy from season 1 in his coat's pocket.
Wataru is sweet and honest, but very spoiled. His sometimes spoiled behavior may be due to the over-protection of his older brothers, as seen that he is very playful. He has a confident personality, as he tries to get Ema's heart among his brothers.
He is also quietly determined, willing to persevere in the battle for Ema's heart. He is also aware that his age serves as limit in the contest, but is willing to wait and make his move when he is older.
Wataru first appeared differently in the Anime and Novel. In the light novel, he accidentally bumps Ema and Juli, who is driving a bike, near the Sunrise Residence gate, later, he introduces himself with Masaomi and apologizes. In the Anime, Ema saw Masaomi and Wataru in the gate, saying hello to her.
In season 2, Wataru called Ema, whom he met near an arcade in the mall. They talked for a while, and saying she shouldn't call him Wataru-chan anymore, despite that now that he has grown up, he will be Ema's boyfriend really soon, and she should call him Wataru-kun like his brothers.
After their father died, Masaomi became a father figure to him. Masaomi made him his favourite rabbit toy and has a similar one in his pocket as well.
When he first met Ema, he already liked her and was happy when he knew that she was going to be his sister. He is also aggressive towards Ema, firmly stating that he will "become a man who is worthy of her."
Wataru seems to like Juli almost as much as he likes his rabbit toy (Not quite though), as seen in Episode 6 when he took him by the ribbon to look at pictures. He treats him like his rabbit doll.
