It's a Megabrawl

Hard pressed by enemy beasts, Momo rallies her troops to dig in, but a glance at her diagram scroll confirms grim math: over eighty of her fighters are already gone, including the mages who had been at her side. A charging behemoth nearly flattens her before a motorcycle plows straight through it, wiping out the creature and pulling her clear of danger. Turning around, she finds the Renjaku students and Unji's crew storming in to join the fray.

Momo is stunned that the newcomers tear through the opposing forces without bothering with the stage's role pairings or any real formation. Unji shrugs that brawling is simply second nature to his people. Trusting them to mop up, he and Momo break for the castle to smash its crystal as the scenario demands.

The clash labeled Danmara Captives vs. Castle Siege Army nearly ends in disaster as Momo's side is overrun. The arrival of the Renjaku High pupils and Unji's gang turns the tide, sparing Momo and Unji and letting the two slip toward the castle. Reaching the crystal, Momo spots talismans pasted over it, and Unji readies a sword strike. Okarun and Turbo Granny shout a warning to leave it intact, but the blade falls first, and the pair frantically tell everyone to flee.

This installment opens Volume 17 within the Danmara Arc, part of the broader Kintama Hunt Saga. It introduces a long roster of Renjaku High and gang fighters into the battle. The cliffhanger sets up the consequences of destroying the crystal, a mistake Okarun arrives a beat too late to prevent.
