When activated, the switches pop up from the ground and power surges around the tips to close it inside a barrier. The dome also separates from the earth and floata floats around in space. It was first used by [[Leo Akaba]] to prevent [[Yuya Sakaki]] and [[Yuri]] from going inside [[ARC-V (machine)|ARC-V]] to become [[Zarc]]. [[Declan Akaba|Declan]], [[Riley Akaba|Riley]], [[Sora Perse|Sora]], and [[Aster Phoenix (ARC-V)|Aster]] were also trapped with them until Yuya became the [[Supreme King Dragon Zarc (character)|Supreme King Dragon Zarc]], causing the dome to explode and returning the room back to [[Duel Academy (ARC-V)|Duel Academy]].<ref name="ep135">{{episode|Yu-Gi-Oh!
