ちびルコさんはとても大事なことを伝えに来た模様です。今日から元祖編完結に向かって息苦しい展開が続きますがお付き合いくださいませ（゜□、゜）

It seems chibi ruko-san comes to tell a very important thing... Please be patient with the tense development till the end of "the original" part.
(note: a little loose translation)

PLOT TWIST!

PLOT!

RUKO IS A MAN

WHO'S INFATUATED WITH MEIKO!

she came looking for Haku then? To tell Meiko about the evil blond gaijin twins?

I thought Ruko-chan was a hermaphrodite who was more of a girl than a boy...

Anyway...

Ruko: *shakes head* That's not what I'm here for...
Meiko: (;ﾟДﾟ)?!

I call for something comedic. Or Ruko moving away.

I, too, am guessing that Ruko is moving away. Kinda explain why she's not with the rest of the gang in the previous strips (present time characters).
