According to the Oricon site, it looks like the single was no. 5 on their first day.
It's actually pretty good compared to the other more-popular artists that released their singles on the same day. I think that Yoake no Ryuuseigun's eventual total sale of numbers won't be determined by how well they do on the charts in the first few weeks though. Pokemon is definitely gonna play in the theaters for a while due to its popularity with kids and families so I think that's something else to look out for.
