Kirbopher

Christopher Niosi, also known as Kirbopher, is an American animator, voice actor, and a collaborator with the SiIvaGunner channel. His involvement with the channel began with the rip "Agent Yoru o Yuku - THE iDOLM@STER" for April Fools' Day 2017.

Niosi's web series Terrain of Magical Expertise (abbreviated TOME) was the subject of a channel event on the series' birthday on November 11, 2017. Kirbopher responded positively to the event, commenting heavily on rips uploaded for the event and Tweeting his thanks.

TOME
The first rip using TOME was "Hot-Head Bop - Donkey Kong Country 2". On the animated series' sixth birthday on November 11, 2017, the channel uploaded 15 rips featuring TOME, bringing the total to 16. Kirbopher maintains a playlist of all TOME SiIvaGunner rips on his YouTube channel.

Agent Yoru o Yuku
According to Niosi's video log "The Story of 'Nico Nico GRAND DAD' - Kirblog 5/2/17", Kirbopher met MtH and other members of the team through a comment of his on the rip video "Pokémon Fainted (Beta Mix) - Pokémon Diamond & Pearl". Kirbopher pitched a collaboration, and the result was "Agent Yoru o Yuku - THE iDOLM@STER", a SiIvaGunner-themed parody of Kirbopher's parody of "Kumikyoku" called "Nico Nico Douga - Kirbomix~".

In order to produce the collaboration, Kirbopher called on several different musicians and voice actors, including some involved in TOME. After the video's upload, Kirbopher joined the SiIvaGunner Discord for two hours.
