Silence (The Jenny Everywhere Roleplaying Game)
From Jenny Everywhere Wiki
Silence was a companion to one incarnation of Jenny Everywhere, who also travelled in the company of a Michael Wherever, Richard, ShatterScreen and Delta 22-6. She was a ninja, dressing all in black, and the tallest member of the party.
Their group, while using an empty warehouse as a base of operations, was forcibly teleported to the testing complex where they had to compete with the team of the Jenny who travelled with Odious. Some way into the trials, however, the older team managed to convince the band shirt Jenny's team that they meant them no harm, and got them to instead sit with them and discuss which would concede to the other for the portal.
