The Abyss of Life

Lord Yoshii Toranaga leads his army back to Edo following the passing of his son, Nagakado.

His trusted general, Hiromatsu, expresses his discontent with the surrender plan in a private meeting, revealing a growing dissent within the ranks.

Hiromatsu's opposition spreads, causing further division among Toranaga's vassals. He even goes as far as threatening to end his own life if his demands are not met. However, Toranaga remains steadfast, refusing to yield to Hiromatsu's ultimatum.

In a cunning move, Toranaga deceives Father Martin and the Catholics by constructing a Catholic church adjacent to the teahouses promised to Madam Gin. This strategic maneuver showcases Toranaga's shrewdness despite his weakened physical state.

Meanwhile, Blackthorne seeks alliances to further his own ambitions, approaching Yabushige with an offer to sail under his banner instead of Toranaga's. Despite initial reluctance, Yabushige considers Blackthorne's proposition, signaling potential shifts in alliances.
