Matsu Muhō (lit. "Wild Matsu"; previously known as RubilacEx) is a contributor to the SiIvaGunner channel and a backroom member.
The first of Matsu's rips that was uploaded to the channel was "Mr. Batty Twist - MOTHER 3". He was added to the SiIvaGunner team a few months later.
On June 21, 2016, for the rip "Main Theme (OST Version) - Mighty No. 9", he suggested the use of "mm2wood.mid", a file a friend of his found when looking for bad MIDIs. mm2wood.mid would later become a meme during The SilvaGunner Spooktacular Halloween Horror Special and The SilvaGunner Christmas Comeback Crisis, as the theme associated to the character Wood Man.
He organized the album il settimo grande padre along with ShonicTH: it was released on September 2, for the 22nd anniversary of Live A Live. He also organized April Fools' Day 2017 and the "Bad Apple!!" event day on May 20, 2017.
The events he contributed the most for were the Halloween Horror Special (10 rips, including 7 rips of games from the Castlevania series), the Inspector Gadget Takeover (9 rips, including 3 for the Bad Apple!! event day) and Bean Mourning Day (2 sad rips and 3 Jojo rips for a total of 5).
