How Did This Assassin End Up in a Girls' Band?

[MyGO] + [Bocchi the Rock!] + [Ave Mujica] + [Girls Band Cry]

Lin, codename Ψ (Psi), known as Psyche: a humanoid weapon whose everyday job is to send targets off in style. His new orders send him to Japan as an exchange student. His mission: find the Resonance Stone!

After doing dirty work for so long, he'd almost forgotten he was still high-school age... It shouldn't be that hard, right?

But fate played a joke on him:

Takamatsu Tomori: “W-will you... form a band with me... for the rest of our lives?” (Lin: ?! This is more nerve-racking than defusing a bomb!)

Goto Hitori: Usually curled up in a corner like a mushroom, but when her social anxiety hits, she unconsciously clings to him like a lifeline! (Lin: ...This feels... pretty nice, actually...)

Toyokawa Sakiko: “Why is all you ever think about other people?!” (Lin: Go eat your boxed meal!)

Shimokitazawa's angel, Ijichi Nijika: “Lin, you're such a good kid~ Want to join my band?” (Lin: Maybe next time... Next time, for sure!)

Kita Ikuyo: “Nijika's right! Join us, join us! I'll perform my omelet-rice magic for you every day!” (Lin: I have to admit, that's tempting...)

Iseri Nina: “Hurry up and start a band with me!!!” (She grabs a speaker and starts swinging it around.) (Lin: ...Where did this kid come from?!)

And so began the most absurd, tone-shattering chaos in history:

A top-tier assassin calibrates a sniper rifle with one hand and tunes a guitar with the other!

When the urge to protect overcomes the instinct to kill, and a career in a band proves more eventful than an assassin's résumé...

Who will the deadly blade known as Psi ultimately defy everything for?

This over-the-top band showdown, composed of lies and the heartbeats of young girls, is about to explode onto the stage!
