Nishikado Sousaburou

Nishikado carries himself with the confidence expected of the Bamyuu 4. He participates without hesitation in the group's dramatic approach to romance and treats Roboco as someone worthy of the attention of Bermuda Town's elite elementary-school boys.

His individual personality receives less development than Toukasa's or Motsuo's. Most of his characterization comes from his place within the quartet, where polished appearances, wealth and excessive romantic confidence are deliberately exaggerated for comedy.

Nishikado nevertheless appears genuinely interested in Roboco rather than merely joining the group for appearances. Her unusual design and behavior do not discourage the Bamyuu 4 from treating her as an attractive romantic prospect.

Nishikado is an ordinary human and has no established supernatural abilities or combat techniques.

His principal advantages are social rather than physical. He belongs to the Bamyuu 4, a group defined by its members' wealth, handsome appearances and elevated social standing. These characteristics are exaggerated as part of the series' romance-manga parody rather than treated as literal powers.

Nishikado appears during Bondo's attempt to discover why Roboco has recently been behaving suspiciously. Bondo secretly follows her through the shopping district, only to discover that Roboco has developed friendly relationships with numerous people around town.

The situation becomes stranger when Toukasa and the Bamyuu 4 arrive. Nishikado joins Rui and Motsuo as members of the quartet, with the revelation of Motsuo's membership linking the supposedly elite group directly to Bondo's ordinary circle of friends.

The boys' interest in Roboco transforms the chapter into a parody of romantic dramas centered on wealthy, handsome students. Nishikado primarily functions as part of that ensemble rather than receiving an independent subplot.

Myouji Toukasa leads the Bamyuu 4 and is Nishikado's fellow member in the group's pursuit of Roboco.

Rui Hanawaza is another member of the Bamyuu 4 and appears alongside Nishikado as part of the quartet.

Motsuo Kaneo completes the Bamyuu 4 with Nishikado, Rui and Toukasa, despite also being one of Bondo's closest everyday friends.

Roboco attracts the Bamyuu 4's romantic attention, with Nishikado participating in the group's efforts to court her.

Bondo Taira encounters Nishikado while secretly following Roboco and witnesses the Bamyuu 4's interest in his OrderMaid.
