She looks cute with twin tails and a side ponytail!

What's that pointy thing in the last panel?

Tweezers holding a cotton swab soaked with something.

Cleaning a wound. That's blood.

Ponytail, Sidetail, Long, and Twintail in that order.

The background of the panels seems to correspond to certain characters, thus implying that the hairstyle in the panel was that certain character's idea.

Panel 1: Hakurei Reimu
Panel 2: Yakumo Yukari
Panel 3: Remilia Scarlet
Panel 4: Nagae Iku
Panel 5: ?
Panel 6: Yagokoro
