It was... an extremely arduous walk for a wide variety of reasons. Ichiban tended to be flanked by his Fatui guards when he was still a Harbinger, so just walking on his own with Ei made him feel extremely exposed. He also didn't really understand just where exactly they were going, so his mind defaulted to the worst possibly scenario... and then there was the fact that there were still Fatui agents in Inazuma, based on the amount of Mirror Maidens he managed to avoid while he was hiding next to Ei. It was honestly really stressful. (He hoped that The Doctor was being truthful for once when he told Ei that the Tsaritsa would not order his recapture...)
For the most part, though, he had nothing to fear. Mostly because... well... Ei tended to get a bit heated whenever people tried messing with her son. You'll get to see why in just a second, actually.
"...What is this supposed to be?"
Ei said, crossing her arms as she saw a group of nobushi—that is, disgraced samurai and ronin who turned to banditry—surround them both.
"Are you vagrants still here after so many years? I must say, I'm quite disappointed..."
"Shut yer trap!" One of them shouted. "If it weren't fer you doin' absolutely nothin', maybe we coulda been somethin' by now! It's all yer fault!"
"...Is that what you think? Honestly, you sound like a whining, pathetic coward to me."
So Ichiban scoffs, looking at his hand in a dramatic gesture.
"I bet you believe that so wholeheartedly... It must make you sleep easier at night blaming everyone else but yourself for your own problems. What's it like, hitting absolute rock bottom?"
The irony of this was lost on Ichiban. Either way, that still pissed off the leader of the nobushi, rushing forward with his sword in an attempt to slice Ichiban to pieces.
"THAT'S ENOUGH OUT OF YOU, YA VERMIN! I'LL SLICE YOU UP AND FEED YA TO THE FISHES—gwuh?"
And that is when the magic would start.
"As if I'd let you get the chance!"
When Ei was a younger, less wiser archon during her years with Makoto and her friends, she played the role of kagemusha, being well-versed in combat of all sorts. Really, her using a polearm and a sword was a requirement of needing to be just like Makoto in virtually all aspects, including combat style and what-have-you. Outside of that, however, she knew almost every martial art that she needed to know. Aikido, sumo, karate, judo, taijutsu—anything you could name, the chances are she's used it once or twice. Hence why, whenever necessary and when really upset, Ei could unleash her wild side, much like she had back in the confrontation against the Akademiya Guards back in Sumeru.
In the instant before the nobushi's leader had gone forth and attempted to cleave Ichiban with his sword, Ei had already disarmed them and was currently holding them by the throat. The leader was making rather undignified choking noises while everyone was watching in shock—and how couldn't they? The Raiden Shogun was a refined woman that fought with minimum waste and maximum grace! How could she fight like a street delinquent?!
"Wh—what're ya—?! Let go of me, ya—"
Reaching forward and grabbing him by the torso with her other hand, Ei had already thrown the leader at another one of the guards, and the remaining three were already advancing on her while Ichiban was standing away watching the carnage happen.
It was a thing of beauty, really. One tried swinging at her face, but Ei expertly deflected it and flipped him over onto the ground, subduing him with a single stomp to the face. From behind, the other guard attempted to cut her horizontally with her sword, but Ei backflipped with grace before launching three palm strikes—once at his elbow to make him drop his sword, once at his stomach to make him keel over, and then one directly up towards his chin, sending him flying. The final vagrant took one look at her and weighed his chances of survival, concluding that there was no way he could win—but chose to try anyway, rushing with his sword...
So, naturally, Ei gave him the most dignified dismissal that she possibly could.
She gracefully side-stepped, poked him in the eyes, and then roundhouse-kicked him in the head, knocking him out cold.
With that, Ei was surrounded by the downed guards, who were groaning in pain. No one would ever believe that they got their asses personally kicked by the Raiden Shogun, which was perhaps the greatest humiliation one could experience.
"...You know, I've got to hand it to you, I didn't realise you were such a good fighter."
Ichiban piped up, walking over and seeming genuinely quite proud of her.
"Well, obviously. The Raiden Shogun didn't get her reputation from just sitting around throwing lightning bolts all day."
"...So why didn't you use the Musou no Hitotachi to get rid of them?"
"Hm... I can think of a fair few reasons."
"Firstly, they never explicitly challenged me to a duel, so I had no right to execute that technique... Secondly, I've no reason to hunt rabbits with a cannon when a dagger does the job just fine... Thirdly, the Musou no Hitotachi can—and usually does—kill people. If these fools have hit rock bottom, then I have at least learned from Lumine that everyone deserves another chance."
"All of these reasons are true in some way or another, but I do confess they're not the main reason..."
"Huh? What is the reason, then?"
"...Maybe I just wanted to show off in front of my son. Who can say for sure?"
Chuckling, Ei turns on her heel and begins walking off towards their destination.
"Let's be off. I'd like to get there at least before midday if possible, provided we don't get any further interventions."
Ichiban shook his head, before following behind Ei dutifully.
He wouldn't admit it out loud, of course, but at times, his mom could be kinda cool.
