Halloween 2018

Halloween 2018 was celebrated from October 31, 2018 to November 7, 2018 with a channel event also known as [???].

Summary
An unknown duo took over the channel. The Twitter account's name and the channel description and Twitter bio were replaced with "???" and "nice?" respectively.

From the avatar, the culprits appeared to be Takane Shijou (left) and Wood Man (right), this would make sense since they were the main stars of previous Halloween events.

On November 7, the video "0000_11_07_2018" was uploaded as a teaser for The SilvaGunner Spooktacular Halloween Horror Special: Part III (originally meant to be an event in January, but was delayed due to the SiIvaGunner Termination), after which everything returned to normal shortly after.
