Old School Ninjitsu. The students are busy cleaning, tidying and polishing the school in preparation for a visit from Shuriken's alumni. While students and staff solemnly wait at the Main Entrance an old man appears, leaning on his cane. This is Aiko, the one and only Alumni member to reply to their invitation. He is overjoyed to see the Cleaning Lady again, his erstwhile sweetheart. The students are astonished too see such a dishevelled Ninja. The Cleaning Lady tells them how Aiko, once a great champion, lost his Ninja spirit.
