Characters

 * Yousuke Toyokawa
 * The main character of the story. He spent the last several years trying to locate his beloved sister, until he found her (sort of).  The biggest clues he has when questioned about his sister's identity is a charm necklace he gave her and a drawing she made with her name on it. Ayu and Mayu both remember having a brother, but they can't remember their brothers appearance. And half the name was torn off the drawing. As the story progresses, he finds himself liking both Ayu and Mayu, wishing they both were his younger sisters.  At one point during chapter one he tries to convince the girls' father that he just remembered having two sisters.  He also tries to get more involved with Ayu and Mayu's lives by getting interested in their hobbies. At the end of Volume one, they found an identical necklace on Ayu's envelope, but at the end of Volume two it seems the name Nayu was written on the necklace. Yousoke is also very hardworking and sometimes takes part-time jobs to support his financials and in the latest chapters he managed to obtain three vacation tickets(?) for Ayu, Mayu and himself.


 * A running gag in the series has it that Yousuke seems to be able to perform superhuman feats whenever he is worked up in a tight situation, when he is on his way to helping his "sisters" (often portrayed comically). Among of his supernatural feats include running very fast on water, and chopping a tree down with only his bare hands as displayed in chapter 13. As of chapter 16, it is also shown that he can even transfer fevers to himself, as how he performed it on Ayu.


 * Mayu Anjou
 * One of the two girls who could have been Yousuke's sister. She is skilled at the violin and plays it at a professional level (seen in chapter three).  She is really close to Ayu and likes that Yousuke tries to be a big brother to her.  Of the two girls, she is the only one that calls Yousuke "onii-chan" (lit. "big brother").  The manga also shows that she is more caring than Ayu towards Yousuke.  This is shown more in chapter 7 when she plans Yousuke's birthday party.  In Chapter 8 Yousuke tells Mayu of his unbrotherly feelings toward her and he feels he has been rejected and suddenly she invites him to go on a beach trip over summer break.  She gives him a test of his feelings and they end up together and sharing their first kiss.But when Ayu finds out that the necklace has "Nayu" engraved in it thy are back to square one and Mayu didn't seem to mind it at all.
