Terumasa Learns His Grandfather's True Heart!!

Under a domain reform that puts ability first, Chokkaku's father Kotayū is promoted from stable duty to head of the petty stewards. Meritocracy reaches Hagi Meirinkan too, and Hosokari rises from homeroom teacher to vice-principal. Then the new term begins. Terumasa arrives out of the sky on his glider, the "Adobarin," bursting with high spirits, and shows Chokkaku a map of the world. Chokkaku is astonished: the world is so vast, and Japan so small.
