[Ryoma didn't bother to introduce himself for his first few days as a member of UG, because it wasn't like it was his idea to join these guys. Dr. Saotome had insisted on it, just as he insisted on Ryoma piloting Getter Robo in the first place. He was beginning to wonder why he let an old, out of shape guy half his height boss him around, but considering the Doc just lost a son, he'd decided not to get too argumentative about it.

At any rate, he's apparently willing to get chummy now. ...Sort of. He's walking around Sakihama Base, cheerfully(?) accosting everyone he bumps into.]

Hey, you! Looks like we're gonna be on the same side. I'm Ryoma! So now that we're buddies and stuff I need you to fill me in.

Who do you think are the strongest fighters in UG?

[Unless there are regular tournaments, after all, this sort of thing can be a matter of opinion. He doesn't mind compiling an oversized list. It'll just give him an excuse to narrow it down.]
[That helpful fellow from the mission at the mysterious dome is at Sakihama now! In a cell. Shackled. Under guard and extensive surveillance. Negotiations between Dr. Saotome and the several groups interested in throwing the guy into a deep, dark hole and letting him rot are ongoing.

So yeah, he tried to steal the Getter and attack Saotome Labs as a distraction to cover his escape - while everyone else was already dealing with the dead and wounded from the bizarre flesh-doppelgangers' attack. And yeah, even before that his terrorist squad killed several guards on their way up the mountain to raid the Labs. And yeah, if you have any access to official security memos or the like, you may be aware that said raid was the culmination of a campaign that started with radicalizing a fair chunk of a university campus and led through multiple bombings and an attack on a government ministry in which many public servants were gunned down in cold blood - and one of his own subordinates was left behind with life-threatening injuries and most of his face missing.

But surely an eloquent appeal to common decency and human compassion will set him straight!]

[Something really weird and worrying happened over the town of Shin Tanoura. Almost the whole town, and its surrounding area, is covered by a large, opaque black dome of some kind of energy, which appeared almost instantly overnight. The contact with the several thousand people inside has been completely cut off, and the initial search team sent into the dome didn't return...
This situation reached the news, and it reached Unity Group's ears even earlier. ESUN has established a research camp near the place, to figure out what the hell is going on - the camp is guarded by a bunch of mecha, just in case. The near Saotome Labs sent several researchers to help, but not too many, as Dr Saotome seems to be busy with other matters. What exactly, he doesn't specify.
Are you just reacting to the news about this? Or maybe you're at the camp, evaluating the situation? Just don't get close to the dome! A guard would stop you if you tried, anyway.]

[Some kind of commotion is going on at Saotome Labs. What could it be? Perhaps it has something to do with the reports from a nearby research camp. Regardless, the whole place is more chaotic than usual, and the security laxer... A perfect opportunity for a group of terrorist students to make their move.]
