I am a student of an English school in Yotsuya, Tokyo now. This is the second time to go to school in this town. The first chance was nearly 20 years ago when I was preparing to enter the college. Now I cannot make sure I really was adulterated enough since many years passed. When I was a prep school student, I often have been to Tokyo Gymnasium swimming pool, Sendagaya throughout narrow streets with tiny old temples between Yotsuya and Sendagaya. Since there were a lot of good swimmers, I became to swim butterfly in later that year, despite my preparing was not necessary to be improved. And a bewitching big red lantern (a sign of drinker) which I felt nothing at that time emerged suddenly.
