Japanese Skill Name: 障壁
Transliteration: The furigana tells us to read it as 'Wall.'
Description: It can be cast to set up an invisible wall that completely shuts out all players and nullifies and deflects all attacks from those players. Can be leveled from I to X (Roman numerals). The higher the level of the skill, the higher the level of players that it repels. The settings can be altered to allow varying degrees of entry (ex. allow customers into the shop, but repel/expel anyone with a weapon equipped).
First Appearance: It is mentioned in Volume 1 Chapter 2 that a Wall X was in place around Tsuki no Hokora.
