S4·E9 Ninja Ryukenden (Ninja Gaiden)

In this episode, Arino returns to another classic NES game. This time it’s the fan-favorite Tecmo game Ninja Gaiden. With a victory here, he can bring his record for the season to a tie, but the Ninja Gaiden series is considered one of the hardest game series ever made. After some time Arino comes to the realization that it may be the hardest game he's ever played in his life... even harder than Ghosts 'n Goblins and Adventure Island! Arino pays a visit to a nostalgic little arcade with a odd name which is enjoyed by children and adults alike. There he discovers a prize machine filled with a cornucopia of pop culture icons and some strange decorations adorning the outer wall.
