In a room where an ancient clock ticks away the time, Taikobo sits facing Ohtenkun, who asks him what his choice will be. Ohtenkun's question leads Taikobo on a journey through his own memories... and each of those memories is linked to Ohtenkun's. Yozen, Supushan, the Buseioh, and all the others Taikobo has met face him in turn. Eventually, after a span of time in which past, present, and future seem to intermingle, the mysteries of the Hoshin Project's history come unraveled.
