Tonagura! (2006)

Kazuki has been awaiting 10 years for the day when her neighbours moved back to their old house. She has a crush on Yuuji, whom she considers as her first love but to whom she never managed to express her feelings for him before they moved out. Yuuji often comes over to play with Kazuki, Kazuki’s older sister Hatsune and Yuuji’s sister Marie when they were kids. Her ideal depiction of Yuuji was soon shattered when he turned out more than she had expected, him acting all ecchi during their reunion. With their parents off in South America, both families must learn to live with each other and rekindle the childhood feelings they shared together. Things get even more crazy as they attend the same school.

Kazuki Arisaka kann es kaum erwarten, ihren Kindheitsfreund (und ihre erste Liebe) Yuuji Kagura nach 10 Jahren endlich wiederzusehen. Voller Hoffnung, dass er zu einem attraktiven und netten Jugendlichen herangereift ist und ihre Gefühle erwidert. Doch zu ihrem Entsetzen hat sich Yuuji in einen Perversen verwandelt und macht es ihr damit nicht gerade einfach, die alten Gefühle wieder aufleben zu lassen. Zum Glück hat sie mit Yuujis kleiner Schwester Marie und ihrer großen Schwester Hatsune zwei Mitstreiter auf ihrer Seite, die beide - wenn auch mit etwas unorthodoxen Methoden - versuchen die Protagonisten zusammenzubringen.
