S1·E5 Shuri's Losen

Once inside the maze tunnel, Sarasa had to face many obstacles and found an old man trapped there for so long. Leaving an eagled embedded ring to be given to his surviving family in Kyushu, he quickly died as Sarasa journeys on to Kyushu. Arriving at the city via the sea, Sasara found a guy named Hayato who's masquerading as Tatara. Elsewhere, Shuri is planning to build a sewage system which will benefit his people. While planning it, Shuri realizes that Tatara may be heading to Kyushu through the ancient underground tunnel and ordered Shidou to act fast.
