Vent or be Vented is the eleventh episode of Gallantmon Strikes.
Kurt explains to Ben that Gakkmon was Vented. Kurt returns home, his father appears again & asks Kurt if he's sure he knows the truth. Ben tries calling Charmin Fearow, but no answer. Daniel asks Ben what did Murmuxmon do to trick a guy like him into this mess. But Ben doesn't know who Murmuxmon is, so Daniel explains that Murmuxmon is the man who gave him his Digi-Deck & tricked them into fighting for him. Daniel says that if they take out Murmuxmon, the war's over. But then Daniel asks Ben to help him defeat both Beelzemon & Murmuxmon. Ben doesn't trust him & takes off.
Morgan & Tom find information in the Tabloids about the appearances of a Costumed Hero keeping Gramercy safe (Depthmon). Tom is jealous that Morgan is now calling Johnny "John". Mira Watson calls Morgan & tells her that she was expecting her transcriptions at her interviews days ago. She asks Morgan if she is working on another story & explains that WayAboveTopSecret won't accept any more of Morgan's stories until Morgan runs them by her. Morgan has Tom ring the bell & tells Mira that she has a customer then hangs up. Mako leaves Kurt's apartment. Morgan tries to call Kurt but he's asleep, so she leaves a message on his answering machine. Morgan comes up with an idea to try to get this Holder to show himself. Kurt awakes & finds that Mako isn't there anymore.
Charmin still isn't answering Ben's calls. Charmin appears behind Ben. Ben tells him that he knows his name's Murmuxmon, & there's no such thing as Battle Club.

Murmuxmon reveals his true form & tells Ben to Vent or be Vented.
