This game was first released as 仮面の忍者 花丸 (Kamen no Ninja Hanamaru
) which roughly translates into "The Masked Ninja Hanamaru".
In this version of the game, you play as Hanamaru, a young masked ninja, who is sent to a children's theme park called Leisure Land, to investigate why all the children have disappeared. When he discovers that other ninjas have kidnapped the kids, Hanamaru sets out to rescue them.
The primary title for this game is Yo! Noid
because Capcom teamed up with the Domino's Pizza company to promote their mascot. When this game was originally released in Japan, the Noid was nowhere to be seen.
