The Undercoders studio showcased the first boss of Denshattack! — Yoshi from the Dashing Queens team. Before the game's release on July 15, the developers shared more details about the fight that opens the series of regional clashes in this action.

Denshattack! is a dynamic trick game where you perform kickflips, ollies, and grinds right on a train. The events unfold in a vibrant dystopian version of Japan, and the player's goal is to earn points, complete tasks, and outpace opponents to become the best Denshattacker.

Yoshi is an influencer from Fukuoka whose popularity became so notable that the authorities considered her a threat. Her image is built around the gyaru aesthetic — a Japanese subculture that emphasizes brightness, volume, and self-confidence.

This is evident in the character's appearance, her train, and most notably in her transformation. In battle, her train merges with fighters and transforms into a huge mecha in the magical girl style, complete with bows, stars, and hearts.

Each boss in Denshattack! is structured as a separate arc with different phases. In the clash with Yoshi, the player first uses tricks and combos to reach the main stage of the fight, then quickly changes tracks, dodges attacks, and counters with grinds and ground pounds.

A separate musical theme was also recorded for this scene. It was created by composer Sean Bialo, leading Vocaloid producer Yunosuke, and pop singer and real gyaru idol Alice Peralta.
