First of all, I think the Shikon shard boosted Tetsusaiga.
And second, Sesshoumaru-sama aimed at that big youkai,
you know, the one with those big round red eyes. I liked him.
The Sesshoumaru-sama attacking Kagome... hm...
I still think it's mostly because of the Shikon shard in that arm.
And it wasn't as strong when aiming at Kagome,
since that big youkai was really BIG... if anyone remember him?
I also think they should get some new attack.
Though I remember Ranma in Ranma½ didn't have more than 3,
and still it became one of the worlds most popular manga.
Nekoken - Ranma's first attack... I'm still laughing while thinking of it.
Amaguriken - Hitting one's opponent with 100 punches per second. cool
Hiryuu Shouten Ha - Another cool attack which looks a little like Bakuryuuha...
He had some more attacks, but he only used them like once.
These three were some standard moves for Ranma.
