Six Ksitigarbha Fusion

Narumi Yatadera's Last Word (a Touhou LW original). She combines with her golem helpers. She usually only uses one golem at a time, but in this attack, she gathers them all together to fuse them with her own body. Combining focuses all of their magical energy, letting her deal out super powerful attacks.

A certain war god once remarked that it would be more effective to attack with each golem in unison rather than combining into a single target, but the wind priestess refuted this, saying this was so much cooler. Narumi, however, seems to have just based this attack on Ksitigarbha, who is also known as Lord of the Six Ways.
