Marco Ikusaba

Marco Ikusaba (戦場 マルコ, Ikusaba Maruko) is a character from the anime Future Diary (Mirai Nikki). He shares the position of the Seventh Diary Holder with his girlfriend/partner Ai Mikami. Together they use the "Exchange Diary" (a paired set that predicts each other's futures and actions), making them a highly coordinated and dangerous duo in the survival game.

Marco is a tough, skilled street brawler with a cocky, energetic, and fight-ready personality. He is deeply devoted to Ai, viewing their love as perfect and unbreakable—he's willing to risk or sacrifice everything to protect her. Their tragic backstory involves being orphans who found family in each other, and their bond drives much of their actions throughout the series.
