Apparently Haku is a youkai that feeds off of human souls. Triple "haku"-age going on here... (
HAKUdoushi, Ko
HAKU, and
HAKU the youkai)! Kohaku thinks back to where he and Kagura had been talking before. In the flashback, they've found youki crystals (much like from Gakusanjin), and she mentions fuyouheki again. The crystals will help them find the baby.
Hakudoushi and Kohaku are travelling together, and they see also see human souls. Hakudoushi says that they've been eaten by the youkai Haku, and he's hunting. So... Hakudoushi kills it. o_O! He tells Kohaku to split its stomach open and look inside.
SASHIMI!!!
Ironically, "HAKU" in this case, literally means "soul."
HAKUDOUSHI: These are human souls. Prey for the youkai Haku.
KOHAKU: Souls...? (hehehe, I honestly don't know if he's saying "souls?" or the name. XD Darn you, Takahashi!)
HAKUDOUSHI: So then, how shall we use these...
Haku haku haku...
AND THEN... ABOUT FRIGGEN TIME HE SHOWED UP!!!

Gah, I'll talk more about Kouga in a minute...

KOUGA-TACHI
Kouga-tachi are investigating the remains of several dead youkai. Kouga mentions that the blood of the youkai they've smelled is pretty new, so whoever did it must be close. He's not sure if it has anything to do with Naraku, since they haven't had any clues in a while. (Well, yeah... you disappeared off the face of the earth for a while there, Kouga!) Hehe.
They get attacked by a youkai...which appears to be made up of youkai remains (Franken-youkai) and they fight. YEI FOR FIGHTS!
INU-TACHI
...Okay, poor Inu is getting hounded by Shippou about what he talked to Kikyou about. I think Shippou is more of a pain than Kagome now! XD But privately, Kagome also wonders what they talked about.
Anyway, it's treated a bit comically again. Pretty much, Sango is saying to Miroku, "Is it just me, or is there something in the air?" To which Miroku says, "Just put up with it. It's always like this."
INUYASHA: Hey, Kagome. You can't be upset forever.
KAGOME: (making "that look") I'm NOT upset.
INUYASHA: So what's with the attitude?
And then he pretty much tries to tell her again that he and Kikyou didn't talk about anything "shady," to which Kagome gives him more attitude, tells him to just be quiet. Bleh. Attitude, attitude, woman.
INU-TACHI MEETS KOUGA-TACHI
So then Inuyasha (literally) gets wind of Kouga. And they go to battle. YEI FOR FIGHTS! And then they meet Kouga. Priceless expression on Inuyasha's face. "WTF?!" And they see him fighting, when something comes out of the youkai, and that's where the chapter leaves off...
