The heroes' Halloween plans are derailed when the latest Oni Mask ends up on Irma's little brother Chris. With help from a visiting El Toro and Paco, they must get the mask off him before it's too late.
- Adaptational Badass: Unlike in canon, Paco actually fights by using wrestling moves he has learned from El Toro.
- All Just a Dream: Invoked. Chris is knocked out when the Oni Mask is removed, so the group lead him to believe that he was just dreaming the whole thing.
- Back-to-Back Badasses: Jade and Irma as well as Jackie and Caleb when they first fight the Squidkhan.
- Big Brother Instinct: Irma is at the forefront of rescuing her little brother from the demon's influence.
- Bound and Gagged: Irma ends up this way with shadows when she's captured by the Squidkhan under Chris' command.
- Canis Major: Jade uses the Monkey Talisman to transform Scruffy into an actual Cerberus to face off against the Squidkhan.
- Crazy-Prepared: Jade brings along the Monkey Talisman so that she can turn Scruffy into Cerberus as a Halloween prank, and the Ox Talisman so that Paco can spar with her evenly with her Guardian strength. Both of these come in handy for the chapter's fights.
- Eye Scream: When Wong sweats due to being close to Taranee's fire, Irma directs the sweat to pass over his eyes and cause him pain.
- For Want Of A Nail:
- Chris gets the Squidkhan mask instead of Paco.
- Because Yan Lin is handling the trick-or-treaters for them, Uncle and Tohru can focus on making the Squidkhan mask removal potion, and don't accidentally give away the key ingredient after mixing it up with candy.
- Girls Have Cooties: Chris has this mindset about being hugged by Irma, so she bombards him with kisses all over the face to mess with him.
- Halloween Episode: An adaptation of JCA's canon example. The author's note even acknowledges the shame that the story's update schedule wouldn't allow for it to be published on Halloween.
- He Is Not My Boyfriend: Jade makes this protest about Paco when she reveals that the two are pen-pals, and gets teasingly asked if they're just pen-pals.
- Hypocrisy Nod: When Paco challenges Oni-Chris to a one-on-one wrestling match yet secretly continues using the Ox Talisman, he feels himself to be a hypocrite for using it (and he himself stopped admiring El Toro when the latter was proven to be winning his matches with that same Talisman) even though he knows this is a life-or-death situation.
- I Know Mortal Kombat: Chris is a big luchador fan, and when wearing the Squidkhan mask is able to give Paco with the Ox Talisman a serious fight.
- In Spite of a Nail: Chris ends up with the Squidkhan mask instead of Paco, but the wearer of the mask still ends up in a luchador fight.
- It's All My Fault: Irma blames herself for Chris putting the mask on his face due to not keeping an eye on him. Jackie tries to comfort her by saying that he should have taken the mask immediately to Section 13 so that no-one could find it at the Silver Dragon.
- Let's Fight Like Gentlemen: In order to stall for time so that the other heroes can bring the mask removal potion for Oni-Chris, Paco plays on Chris' admiration of luchadores and challenges him to a one-on-one wrestling match. Oni-Chris dispatches his katana on Paco's demand, but Paco secretly uses the Ox Talisman even though he's not proud of it. Once Oni-Chris finds this out, he tries to kill Paco for cheating.
- No More for Me: After Chris uses the Squidkhan to scare a man and rob him of his candy, the man says that he needs to lay off the Red Bull.
- Punctuated! For! Emphasis!: Irma when she tears off the Squidkhan mask from Chris' face.Irma: I. Want. My. Brother. Back!
- Skewed Priorities: When Hak Foo demands that the Guardians hand over the Squidkhan mask, Hay Lin says that since he's already orange it won't work with his skin tone. Jade dryly notes that shouldn't be the main reason they're not giving him the mask.
- Super Window Jump: Oni-Chris flees from the Silver Dragon by backflipping through a window.
