The all-Japanese cast aligns organically with the modern Japan setting, featuring no race-swaps, gender-swaps, or forced diversity changes to established elements. A single recurring supporting character, Yu Kamimura (donut shop manager), embodies the common Japanese 'onee' trope (flamboyant, effeminate personality) and is played by transgender actor Kaba-chan, marking a minor incidental LGBTQ+ presence that serves comic relief and ally support without any plot focus on her identity, lectures, or activist framing.

This element feels organic to Japanese media conventions rather than imported progressive activism, appearing in background interactions without influencing character arcs, premise, or emotional core. Reception lacks any 'woke' backlash, creator-stated intent for inclusion mandates, or audience complaints of preachiness; it's praised for entertaining fights and storytelling unburdened by contemporary ideological intrusions.
