They currently have a mean of 5.8 so far, so I can really see Yui getting the #6 spot on Tuesday. However, we don't know anything about the amount of copies sold, so I can literally be anything.
Baito Fighter has a mean of 5.6, which means they could either ger #5 or #6. But at least they have some reported sales (12,305 so far).
But fripSide seems like the winner for #1 spot for me.
It is no surprise fripSide is doing well. That single is tied-in with Toaru Kagaku no Railgun, which is very popular. I think it has to do with the Misaka "sisters" story arc ( http://toarumajutsunoindex.wikia.com/wiki/Sisters_Arc )
Update: fripSide's single is the OP for Toaru Kagaku no Railgun S, the new Railgun series.
To bad Misawa Sachika's mini album Polaris which was tied to the movie didn't do so well. It had alot of good songs imo. This is my favourite Telepath~Hikari no Tou~ [youtube]p98PjGil_R0[/youtube]
Update: I'm listening to fripSide's "Sister's Noise", its similar to their previous hit "Only My Railgun". No wonder its doing good [youtube]UhtWs0wsNOc[/youtube]
anyways 2013年5月12日 - 9位 They have a mean of 6.33.... right now, #6 could be very probable, but yet again, we don't know how many copies it might have sold.
