Lupin III: Part 6 Season 5 Episode 22

Answer Me, Zantetsuken

PeopleLog has stirred doubts within Goemon about whether Lupin sees him as an equal partner, but he still rejoins Lupin, Jigen and Ami to infiltrate the headquarters of Shake Handz on Olig Island in the Republic of Maul. Ami initiates a massive DDoS on the Shake Handz network system to mask their movements, but Enzo has anticipated this event and executes a counterattack. Goemon, left behind to cover the team's retreat, is challenged by Enzo, who fans Goemon's lingering doubts about his relationship with Lupin. Just as Lupin and Ami are about to liberate Fujiko, Goemon intervenes, demanding a duel to clarify things between them and draws his sword, Zantetsuken. Lupin ends up critically wounded and Ami pleads with Enzo - whom she knows to be her father - to save Lupin's life.
