Calm tones reminiscent of sepia and ink paintings. Main Heroes: Yamato Takeru: A dignified figure wearing a magatama necklace, holding the sacred sword "Kusanagi-no-Tsurugi" in both hands, slicing through the encroaching flames. Momotaro: A brave figure wearing his familiar jinbaori (warrior's surcoat), accompanied by his dog, monkey, and pheasant, pointing towards Onigashima (Demon Island) in the distance. ② Center Left: [Street Televisions and the Frenzy of Special Effects] (Mid-Showa Era: 1950s-1970s) Background/Style: The rounded frame of a retro Showa-era cathode ray tube television.

Main Heroes: Tanjiro Kamado (Demon Slayer): His green and black checkered haori flutters as he takes a step forward, unleashing fierce "Water Breathing (blue wave spray)" from his Nichirin sword.
