Beat that monster up Reimu

Poor monster :(

I wonder how many walls it takes to fully stop a master spark.

Marisa's panicking, Reimu calm.

Also can we appreciate on how good the artstyle is?

Gensokyo - style incident resolution 101: beat the snot out of everyone you encounter*, until you serendipitously take out the party(ies) responsible.
