Nightly Tears of Sympathy (夜話情涙川 Yowanasake Namidagawa) is the fourth episode of Samurai Sentai Shinkenger.
After confronting the Ayakashi Namiayashi who eludes them, the Shinkengers search for the young boy whom the monster made a promise to, a little leaguer named Ryota. Ryunosuke and Mako manage to find him and attempt to talk to Ryota, but the boy refused to answer them and pedals off. Following him to his home to learn whatever secret he has, the two get into a discussion of Ryunosuke's personal regret of his life-long dream that he has been keeping to himself before Mako comforts him, later giving him poorly made muffler and meal as they spend the night at the stake out. The next day, they find Ryota on the move as he suddenly disposes of his baseball stuff and calls Namiayashi as he performs his end of the promise, hurting himself so he cannot play baseball in order to get his grandfather back. However, Namiayashi revealed it to be a lie as part of his plan to make the boy cry to overflow the Sanzu River. Vowing to make the Ayakashi pay, Ryunosuke and Mako transform to fight him as the others arrive. While the others deal with the Nanashi, Shinken Blue and Shinken Pink defeat Namiayashi as he revives into a giant. After the Ryu and the Kame Origami get a shot at him, Shinkenoh is formed and finishes the Ayakashi off. Later, after Takeru uses his Mojikara to ease Ryota as he stands by the sidelines, Ryunosuke is confused when Mako turns him down.
