That panel on page 19 gets me everytime, they knew iruma experienced something and was unwilling to share due to trauma.
Honestly, it makes me love the chapters where iruma just talks to the other misfits.
I think as long as the manga itself doesn’t take itself TOO seriously and stays on the fine line of “weirdly based” and “nice meme” with some dashes of slight emotional depth, it might be a decent ecchi.
