Getting to Mikuo's room was never hard. Like with most of the rooms in the house, Len knew where each one was. In complete darkness, however, that knowledge didn't help him much. After about a minute or two consisting of nearly tripping on objects that seemed invisible, get afraid of imaginary moving shadows and bumping into walls, he found the door that belonged to his "target". Trying to remain mostly silent in fear of waking anyone but Mikuo up, he knocked quickly and as quiet as he could.
"M-Mikuo? Its m-me."
It took a moment for the door to open up, and have the inhabitant of the room look at him with a tired expression on his face, widening barely with surprise.
"…M-Miku? I thought you were g-go-"
Before Mikuo could finish the final fragment of his sentence, Len pressed his bony finger against his lips.
"Ssch."
Without a sign of protest, Mikuo opened up the door for the person unbeknownst to him impersonating his sister. Walking in, Len looked around slightly, trying to not cause much attention, and placed the pile of clothes down on his bed. Turning his gaze toward the only other person in the room, he smiled awkwardly and blushed to add to the effect.
"I-I've been hiding! N-No reason, really! …Okay, I was bored, I suppose. Slept over at my friend's house."
Seeming to take it all in, Mikuo only nodded and closed the door behind him fully, giving them the ability to talk with normal voices. Excessive whispering probably wasn't that good for one's lungs, anyway. Putting his hasted smile aside, he went over to the only bed in the room, and placed down his pile neatly on it.
"…Put them on, p-please."
His gaze, suddenly much more serious, was turned towards Mikuo.
"W-Whaa-"
"Please, brother?"
With a displeased sigh, he looked down on his bare feet. A sudden sense of guilt fell over "Miku's" shoulders as he did. Had she been too straight-forward, or really making Mikuo feel cruel because he didn't do as his sister wanted him to? Preparing to apologize and walk out, he was distracted by the person in the room.
"…F-Fine, if you really wish."
Len noted how Mikuo's hands searched through the pile under the faint light coming from the barely working lamp in some far-off corner in his room. With curiosity, he went through the articles of clothing, only with increasing color over his face.
"…S-Sis, you want me to dress up as y-you?"
Trying to not break into a fit of laughter, or a haunting grin, "she" kept quiet and only nodded subtly.
"…L-Leave me a-alone for a bit, then."
Not wanting to force a remark that "she" was his sister and had seen him naked when they were younger (possibly, Len didn't exactly know), he did as Mikuo wanted. After maybe a minute or two – perhaps even three – he could hear a faint knock from the other side of the door. Taking it as a "clear" sign, he stepped in.
Standing in his sister's iconic attire was quite embarrassing for Mikuo. Or no, it was BEYOND just simple embarrassment for him. Thing was, the clothes in themselves wouldn't have been that horrible to wear (it happened quite often that someone dressed him up in a skirt, or he did so himself), it was rather how it was his sister this time. That, and that she seemed so serious about actually making him dress up as her. Sorting through the pile, he never expected to find prosthetic breasts lying around. A wig was actually not that surprising, but not fake girl-parts! …Where had his sister gotten them from, anyway?
For the sake of his life, he felt it was better not to ask her, ever. Strange questions tended to annoy his sister, a lot. Sure, this time it was her fault, but Miku probably wouldn't react well, regardless. Judging from her healthy blushing when she finally saw him dressed up as her, however, perhaps asking would get along much easier.
"H-How do I look?"
"…E-Exactly like Miku."
Well, yeah, Mikuo was her twin, but- For a quick second he could feel his mind disappear into a distant place. Getting a glance of an exact clone of his sister (except not, he was actually a bit taller) in the mirror was enough to shock him. Collecting himself, he turned around towards his sister, standing shyly behind him. Why was she acting so different from her usual, short-tempered self? Did Mikuo's cross-dressing really affect her that much? Did she see it as a way to have a replacement for concerts if she couldn't go? But, that was something even Miku wouldn't ever do. She knew about his fear of being on-stage, after all. Vocaloid-fans always preferred Miku over him, which he was fine with. Aside from covers of Miku's own songs, they usually left him alone.
Turning his thoughts back to his current situation, he locked his gaze on his sister.
"…W-Why d-did you want me to dress u-up as y-y-you?"
