Keitaro was sitting innocently in his room. He was not bothering anybody, he was not making any disturbing noise, and neither was he upsetting anybody. Well, two strikes out of three aren't bad. Anyway, the door to his small and cozy room was suddenly flung open, and Keitaro lifted his head only to see Naru with her patented "Super Death Glare" turned on at nearly full power. Keitaro immediately cowered under her gaze, and scampered away to hide under his study table, looking for the entire world like a rat that just saw a cat. As he crawled away pitifully, he begged for mercy and for some justification as to why he was going to be beaten. If course, this move merely incensed Naru further, and she turned on her Super Death Glare to full blast, causing Keitaro to nearly wet his pants, before growling a "YOU PISS ME OFF JUST BECAUSE YOU EXIST" and sending him on his way into the hot springs.
Of course, Keitaro had to be beaten whenever he entered the hot springs, even if the springs were unoccupied and his entrance was due to their actions, so Motoko ran in like a speeding bullet and screamed, "HOW DARE YOU PEEP ON THE TENANTS! DIE!" before screaming,
"SHINMEI-RIU OUGI ZANGAN KEN!"
"SHINMEI-RIU OUGI ZANKUSEN!"
"SHINMEI-RIU OUGI HYAKURETSU OUKAZAN!"
"SHINMEI-RIU OUGI HIYATSUKU RYOURAN!"
"SHINMEI-RIU OUGI NITRORENGEKI ZANTETSUSEN!"
With each attack, Keitaro was split, sliced, spun, slashed, stabbed until his skin and flesh were torn, his bones were shattered, and his body feeling the pain of some serious metal. However, Keitaro's brain had long since gone bust, as he struggled to comprehend the usefulness of the Shinmei-Riu attacks when they took at least five minutes to simply spell out each attack. Struggling hard, Keitaro's brain had spontaneously combusted when he got hit by the two prong metal splitting stroke, Keitaro was left a sputtering, twitching mess on the floor, and he was promptly shown the door; the wall, when Motoko finally realized that her torture subject wasn't screaming as expected. As he flew towards the door, his immortal body began to regenerate itself, until he became just another normal human being without clothes.
Right into Su Keitaro flew, and the evil genius did not even bother with formalities; she simply shot him with about 272346123 ray guys, sliced him 2136867213 times with a light saber and stabbed him 1236127324 with a raw uranium laced metal pole. While Keitaro's body battled with the severe wounds and radiation effects, Su summoned her entire legion of hundred ton Mecha Tamas and ordered each of them to jump high before coming down hard on Keitaro's groin. However, Su made sure that Keitaro's brain had recovered and was able to experience pain before sending the Mecha Tamas down. The first attack pounded Keitaro's groin one meter into the ground. Subsequent attacks shook the very foundations of the inn and smashed Keitaro's genitals into a bloody pulp. Of course, Keitaro will recover pretty soon due to his immortality.
Unsatisfied with the punishment, Su grabbed Keitaro's hands; both of which were currently clutching what remained of his balls, and sent him flying right into a tank filled with really concentrated acid. Keitaro's clothes instantly burned away, and he could feel his skin, muscles, and bones melting away. Of course, Keitaro's regenerative factor was unbelievably powerful, so his skin grew back before long. Still, even though he was physically unable to die, Keitaro could feel the pain akin to being roasted alive in a furnace operating at 4000 degrees centigrade. Worst still, he accidentally open his mouth when the twitching got really bad, and the acid rushed right into his body, burning him from the inside out. Still, Keitaro's regenerative factor kicked in fast, and soon he was back to his normal skinny self. The pain did not stop though, especially when his head lost its pressure and the acid flooded in from his ears and nose, burning away his entire brain.
And so it was, Keitaro's body continued to burn out and grow back for a few moments, until Su decided that she had had enough fun and neutralized the acid with some alkalis. The neutralization was not very rapid through, and Keitaro's right eye was corroded to the bone by the alkali, while the still powerful acid burned his left eye away. Finally, Keitaro was left floating around aimlessly in a tank of water, while his body gradually repaired itself back to its normal state. The lack of usable oxygen in the water was killing his brain, but it didn't matter; his immortality prevented him from dying, and his regenerative factor forced his brain to come back to life when it died.
After a few minutes, Keitaro's conscious brain kicked back into action, and he recovered enough to swim back up to the surface. Climbing out of the tank, Keitaro took a few deep breaths before realizing that he was standing in the middle of the main corridor, naked as the day he was born. Leaping to the side, Keitaro was just able to get out of Motoko's field of vision before she swept around. It was not to be, however, as she ran up to him and gave him a hard whack with her sword, sending him through the wall into Kitsune's room.
As soon as she noticed who was in her room, Kitsune took the current bottle of Sake she was drinking and smashed it right on Keitaro's head, before picking up several of the glass shards and stabbing them into his face and body, twisting them around so that Keitaro would really feel the pain. Of course, she knew that Keitaro was immortal, so it was all right to have some fun with the semi-conscious/half-dead/walking corpse of a manager. After demanding more money from the already dead broke manager, Kitsune proceeded to stick some shards into his eyes and twist the shards until she felt bone resistance.
