Inuyasha v54 ch531 "Cloud of Jyaki" (Jyaki no Unkai)
犬夜叉 第531話 「玉の完成」
Prior to departure. Sango tells Kohaku to stay with Kaede, and not mistreat the life that Kikyou gave him.
Likewise, when Shippou is also forced to stay in the village, he is brought to tears that he can't fight with the others.
Inuyasha: "You're our friend, Shippou. So if by some chance we don't come back, you'll finish things in our place."
Shippou: "Eh? By myself?!" Inuyasha: "When you become an adult… a daiyoukai, then sure. You understand, Shippou?"
"But…" thinks Shippou as Inuyasha hits him. The others leave while he's unconscious.
When Shippou wakes up and goes outside, he sees a part of the sky has been covered in jyaki.
Naraku has taken the form of (or is hiding inside of?) a giant spider.
Sesshoumaru stands before him, and kills the attacking youkai with Bakusaiga. Then Byakuya appears.
Byakuya: "If you used Bakusaiga, even transformed, Naraku would be no problem for you. So, what's to hold you back from killing him? Are you worried about your little girl? I guessed as much… She's here. Inside of Naraku."
Inuyasha's group also reaches Naraku.
There, the spider's body opens as if guiding them in.

I only found this series in… let's see… *counting* summer of 2005, so my connection with Inuyasha have been very short
*sigh*
no matter how it ends, I will love it forever and ever and ever and ever *gets shot*
