Artist check - gayarou / hal_(artist)

So I found some nice pics on pixiv that I was going to upload (post #299341 post #388890), and both were already uploaded - which is fine, but both were uploaded under different artist tags, despite being on the same pixiv account (11186). The artist's nickname on pixiv is ミ☆, and the tags used here were gayarou (with 42 pictures) and hal_(artist) (with 54 pictures).

Perhaps someone who knows anything about this person (or persons if the case may be) can say if they need to be merged, or what action should be taken.

(edit)

I think someone just mistagged the one that says Hal, from looking at the Pixiv accounts, Hal is definitely not the one who did those images.

Other than that, the "Gayarou" artist entry is empty other than for the name and "Hal" should be actually 駒燕 (komatsubame), those two need fixing.

Wow, what a mess... I think there's a third one: post #356748

Looks like Gayarou's pixiv account. Nickname is a shooting star, username is fc00929376 which might be something to do with F&C (game company).

Also dubious: is post #89032 drawn by figo or gayarou? The blog entry says this:
