I smell a Master Spark. And by the look on Meiling's face so does she.

I'm gonna miss you Meiling

Good news - it's probably not a Master Spark.
Bad news - that's because that light down in the bottom left makes it look like a Double Spark. An intersecting one, too.

Meiling looks like she might have a plan

Two of my favourite Touhou characters in the same picture - and a rare pairing too.

So awesome.

Yuuka's smile and Meiling's more tense expression does underline the difference in power.
