How would Ennoshita / Yamamoto / Izuki / Riku react to their s/o being captured by a rival gang – the s/o being tortured until they give them what they want, on the expense of their gangmembers?

Ennoshita: So calm initially, the gang thinks he didn’t hear
them. Then his aura changes and they all cower back. The people who hurt you
are gonna wish they’d never been born.

Yamamoto: He cries because he’s failed you, failed to
protect you. But even through his tears, his rage is clear; there will be swift
and thorough punishment dealt to your offenders.

Izuki: There are no jokes, no quips, no puns. He’s hell
bent on revenge and god help anyone who gets in his way.

Riko: When she’s finished, there’s nothing left of the ones
who assaulted her love. Silence fills the room as she return, seeking him first
to take with her for a shower; he to clean his wounds, her to wash off the
blood of his former torturers.
