(Backdated to Before Grand Unified Theory Mission, and Open to All.)
Some time has passed since the Gurren Brigade Tryouts. You haven't heard much about that whole business, despite the big Land Battleship with stump feet that follows the Chalice about.
But then, communiques are sent to all those who expressed interest in taking part in the grand activities of the Gender-Neutral Brotherhood of Manly Souls at the meeting: invites, to be precise! Invites inviting all honorary members of the Gurren Brigade to a military exercise, in which there will be tactical drills, maneuvering practice, a mock battle, and–for those who prefer other such things–free snacks, drinks, and pastries at the end of it!
Those who show up to the Dai-Gurren will find it's own hanger filled with some mechs– a Dorbek and Dogozzo IIC, Matthew's own Nova Messenger, the Juaggu...and a Dom Tropen, stumbling about the relatively cramped hanger like a drunken loon as three familiar people attempt to dodge out of it's way.
"Don't overcompensate!" Matthew shouts up to the Dom's open cockpit, backing away from it with Chandra and Eilena. "Let the mech move itself! Work in harmony with it's Earth Sphere self-balancing software!""Stop throwing Nova Cat claptrap at me!"
Tynall shouts. "Why does this stravag junk-heap not have a neuro-helmet like actual, proper mechs?"
It's tactical drill time! Want to practice anti-mech tactics? Want to practice anti-mech tactics without a mech of your own? Learn how to to dodge things? Show off?
It's mock battle time! Two equally balanced forces, advancing through, a hilly, forested region with a huge lake, asserting supremacy over each other with paint-rounds and dialed down lasers! Who shall prove superior?
Also, a certain individual onboard the nearby Dai-Gurren may randomly decide to bombard you all. With paint shells. We think.
It's snack time! A table of refreshments is nearby! Hor-devores, tiny, sugary pastries, and various beverages! It also happens to be on the prow of the Dai-Gurren, a three-barrel battleship cannon right above your head.
At one point in this quasi-party, Matthew, tapping a fork against a glass for attention, will ask you all:
"Friends, Comrades, Trothkin. If there is one thing we have gained in our time aboard the White Chalice, during great battles and fierce conflicts, in our many travels and constant roaming...it is stories. Stories of others, and stories of our own. And among these stories of ours, the most prevalent story, I have heard, is that of rivalry. Of personal conflicts against other individuals, set against each other by differing ideals and beliefs.
For those who feel comfortable speaking of such things, I ask: what nemeses have you fought against in your time here? What rivals and adversaries have you encountered, and what is or was the mettle of their character?"
