Wall-Phasing

Matthew was curious.

It was a pity that the summoned creatures for advancement or mission rewards were randomly grabbed from the negative energy plane. Miss Ghost could not speak, so he had no way to know her story for the time being.

"Specters should have their own names too. Seeing how you're floating here and there, I'll call you Drifter!"

..

[Hint: Naming successful! The loyalty of the cursed ghost to you has increased to 85!]

[You have returned the right to adjust Beauty is Strength to Drifter. The Drifter is very grateful to you. The Drifter's loyalty has increased to 95!]

[The Drifter has shared her ability, "Wall Phasing Technique", with you.]

[Wall Phasing Technique (Weakened): You can turn your body into a ghost through a preparatory action and pass through a physical wall with a thickness of up to 1.2 meters.]

Warning-

When you pass through the wall, your speed will be reduced to 1/3 of your usual speed.
