Hakuba: Konnichiwa, minna-sama! Kyou hiragana no HA wo benkyoshitai! Tna-chan to Kaoko-chan kochira e ikanai, ja boku wa koko ni iru. Ah- wasurechatta, boku wa Hakuba Saguru, yoroshiku onegaishimasu!
*Cough*
Someone came to the class and coughed. Crossing her hands lazily.
Hakuba: Haibara-chan?
Haibara: In case you forgot, but this is an international classroom, many of them aren't coming from Japan, so please use English.
She glanced at Hakuba sarcastically.
Hakuba: Aha~ gomen, gomen...hontou ni wasurechatta...
*scratching his not-itchy head*
Haibara only responded with apathetic expression without a single word.
Hakuba: Tonikaku, why does the-first-grader come here all of sudden? We're going to teach everyone who is absolutely years and years older than you.
Haibara: Any problem?
Again, she coldly implied Hakuba's words without any expression.
Hakuba: Betsuni...
Haibara: Well, actually Tna-san and Kaoko-san asked me to share about Japanese language to all members of this classroom since my name begins with “HA”. I bet you're here for the same reason.
Hakuba: Yeah, perfectly right. Ja, could we start the class now?
Haibara: Dame yo. We should wait for another teacher.
Hakuba: Maji ka yo? There's another besides us? Dare?
Haibara: Soon you'll see him. Ah, no. You've known him already. Just wait patiently.
Haibara looked at his watch then sighed.
Hakuba: Why hasn't he come? It's been fifteen minutes late,”
Haibara: If he came on time, then it would be weird.
Hakuba: Ha?
Haibara: So, the great meitantei has no idea about him?
She smirked and scorned him.
Hakuba: Taku....
45 minutes passed. Some students in the classroom complained for the very long delay, but some of them seemed to enjoy chitchatting each other.
An hour later...
“Yo, minna!”
A-not-unfamiliar voice with lazy tone heard. Someone came into the classroom.
Haibara: An hour forty six minutes and twenty seven seconds late. Youkoso, Hatake-san.
Kakashi: Aha- gomen, gomen. I helped a granny found her way home. On my way here, I ran into two foreign girls wandering away in my love labyrin-
Hakuba: Uso! Ah, so another teacher is you, Kakashi-san?
Kakashi: Ah, sou, sou.
Haibara: Maa, can we start off now?
Kakashi: Yeah, of course. I brought a nice book with me so we can have fun while learning 'HA' lesson!
He put out three books with different color from his ninja weapon pocket.
Hakuba: Icha Icha Paradise? Kakashi-san, they're still underage! Not to mention one of us also far behind the permitted age... I think mine is better...
He glanced at Haibara. But she just sneered at him, silently. He had no idea that she was actually an eighteen year old woman. Hakuba then put out a blue thick novel-like.
Haibara: Sherlock Holmes? Geez~ I'm freakin' out already with so many Holmes' freak around me...
She sighed with a long breath, suddenly she remembered of Kudou Shinichi, the biggest fan of it.
Haibara: Maa, I think mine is better...
She took out a magazine-like book and showed it off to those two.
Kakashi & Hakuba: EINSTEIN?
Kakashi: We're not going to study science, Haibara...
Haibara: But we're not also going to study ninja arts and detective story, no?
Hakuba: Demo sa, detective story is important to build up their analytical skill...
Cheesus: Ano...can we start now? More than two hours the lesson is being delayed. May I know what's the topic for today?
Haibara: Einstein life story!
Kakashi: Ninja arts!
Hakuba: Detective!
They said accordingly.
Cheesus: OK, OK. Just mingle them into one. So the conclusion is we're going to study "A Detective, who had used to be a mad scientist, was currently learning Ninja Arts".
Hakuba, Kakashi, & Haibara: 
. I asked Doraemon to help us teaching today's lesson with some tools from his 
NOOOOO~ !!
, ne Tna-chan?
. Well, Nobita-kun, please write your name on the board.
. Maa, I think we should continue our lesson without them...
