[Training Arena]

A large wide spread out room, where Servants can spar or dual each other. The arena is heavily reinforced by Casters to prevent damages that Servants may cause to do during battle. Noble Phantasms of Anti-Army to Anti-World are banned. Some Anti-Units Noble Phantasms are ok, as long it doesn't kill or cause too much property damage. Reality Marbles are ok.

Prisma Illya and Chloe von Einzbern wanted to train to become better since they are one of the Youngest Heroic Spirits to be summoned and lack experience, unlike older Servants.

Tamamo no Mae and Archerko agree to help them, with Tamamo training Illya and Archerko with Chloe. They also dragged Shirou along to be an observer, to point out flaws his alter-dimension younger step-sisters may have.

[Hours of Training Later]

Archerko: *clap* "I think that enough training for now."

Tamamo: "I can still keep going."

Archerko: "I know. I was talking about the young ones." Pointing to an exhausted Illya and Chloe.

Tamamo: "oh"

Chloe: "I can't feel body" Sitting on the floor, unable to move. Clashing swords with a sword dancer Onee-chan for long hours wasn't good for her muscles.

Illya: "So tired" She said weakly with her body collapsed on the floor.

Shirou: "Illya, the floor isn't a bed."

Illya: "I'm too exhausted to move an inch" She groaned.

Archerko: *sigh* "I guess we pushed them a little too far. Come on, Onii-chan will take you to your room."

Shirou: "I did not say that I would." Then looks Archerko at the eye. "Your planning something aren't you."

Archerko: "Me? Your only cute little sister in existence would lie to Onii-chan. Of course not~ Your the only guy here, who can pick these girls up with ease. Unless you want us to do more work, while you just stand there amusing yourself at our hard labor.

Shirou: "..." EMIYA couldn't argue against that. "fi-"

Ruby: "I can help with that!" Illya's mystic code interrupted. "I can get her up at 400% ready and going. Beast Mode~!" It cheered.

Illya: Faster than anyone could blink, Illya was already up and screaming. "Ruby STOP STOP!"

Shirou: 'Instant recovery' He noticed.

Tamamo: "Beast Mode?"

Archerko: "I recall Ruby saying that a few times, but not sure what it really is."

Illya: "It's nothing but a Curse." Slowly losing her strength to stand.

Ruby: "It's a power boost~"

Archerko: "How is it a curse?"

Ruby: "I'll show you. Beast mode~!"

A bright white flash surround Archerko causing everyone to look away for a bit, before looking back.
Archerko's clothes and armor was gone and was replaced with a very revealing cat outfit. Much of her beauitful skin was exposed and the noticeable distinct feature was that her bust was bigger than it was underneath her clothes. But not as big as mom, Irisviel.

Archerko: "KYAAA" She screamed and quickly fell on the ground. "W-What the hell is this! This isn't nothing like a beast but a perverted suit. Get OFF from me!" Pushing her circuits into maximizing her magic resistance, kicking Ruby out of her and restoring her natural outfit.

Ruby: "Ah, no need to be harsh big Illya" A sense of danger increasing. "um, Illya?"

Archerko: "I should've never trusted a tool made by Zelretch." A dark aura being release and targeting at Ruby. "Trace on". Tracing a sword very familiar to a legend connected to Tamamo.

Tamamo: "The Ama-no-Murakumo-no-Tsurugi!"

Archerko: "I wonder how you will feel when your cut into a million pieces" Threateningly said to Ruby.

Ruby: "Umm, v-violence isn't the answer Illya. Help me!~" Slowly retreating backwards.

Archerko: "There's no escape." That sentence quickly made Ruby run off flying and she chased after the cursed object.

Everyone else: "..."

Tamamo: "That was interesting..." Breaking the slience.

Illya: "I now know the future will be kind to me" Feeling a bit happy about the future.

Chloe: Looking at Shirou, who was looking at the opposite direction. She decided to play with him, a bit. "So how much did you see, Onii-chan~"

Shirou: 'curse you E-ranked luck' "Nothing much" Maintaining his pokerface.

Chloe: "So you indeed saw, what part of Onee-chan did see? hm". This question quickly attracted to Illya's attention.

Illya: She was getting curious. Her Onii-chan treated her nothing but a little sister but this time they were both adults. What will adult Shirou EMIYA say about an adult Illyaviel.

Shirou: A hit on his poker face and now he can't escape from the question. 'tch' "Nothing you need to worry about for someone young as you" Switching to spirit form.

Chloe: "Ah! He escaped."

Tamamo: "Don't worry, you'll see him again sooner or later."

I wonder if, I should put the rating to an 'M' since the next chapter will be a bath scene.
