Tripeace

Nana, handsome amnesiac youth who has long fair hair and a strong sense of justice, attempts to bring peace to the world. To do so, he attained a Tri-peace operative number (102078) in an organisation of people who stop wars and encourage peace.
Faced with danger and perpetual doubt in whether or not he can truly get the world to be at peace using his good disguise (crossdressing as Nanako), he strives to stop all wars.
