Summary

Naked Week. Just as the name implies, that is a week which you must head to school... naked. A traditional custom of a certain Japanese academy. However, the freshgrads that have only just enrolled cannot handle such a high-level of exhibition straight away... They must first head of to a special training camp so that they may prepare themselves for the humility of nakedness. That is, the Special Training Camp for a Naked Week regime. Also known as... ZENGAKU!! You participate in training camp with the girl that you adore! But what awaits you at the camp is... a full on training regime of humiliation and disgrace!? [From DLsite English]
