"PHASE SHIFT… MOONLIGHT SLASH!" Akira used [Phase Shift], which changed the shape of the surrounding moon, making it go from a half-moon to a full moon again, and also making it more powerful in the process.

[Skill: Phase Shift]
[Rank: Legendary]
[Description: Just as phases of the moon go by, your attitude and techniques must shift as well, this skill allows the user to change his combat method between two current styles (more will appear after level up)]
…
The second style was like this: more powerful attacks, but reducing speed slightly as he was now holding his weapon with two hands.
It was something he used when he was confident he would be able to kill his enemy in one blow, or wanted to make sure the damage would be enough.
And in that case, he truly wanted to cause the maximum amount of damage to Stark for annoying him so much.
