"SOL's Decline" is the one-hundredth-and-twelfth episode of Yu-Gi-Oh! VRAINS anime. It first aired in Japan on July 31, 2019.
LINK VRAINS, which should have been shut down, is now open again, and many citizens of Den City begin to log in. In order to search for clues about Ai, who has taken over SOL, Soulburner decides to investigate LINK VRAINS. There, he discovers an island he has never seen before. On the island is a country filled with household appliances. Soulburner then encounters Roboppy in the country.
Featured Duel: Soulburner vs. Roboppy
The Duel is conducted as a Master Duel.
Turn 1: Roboppy
Roboppy activates the Field Spell "Appliancer Electrilyrical World", whose effect lets Roboppy add 1 "Appliancer" Spell Card from his Deck to his hand when it is activated. He adds an unspecified card. He then Normal Summons "Appliancer Socketroll" (100/100) and then uses the effect of the "Appliancer Copybokkle" in his hand, targeting "Socketroll" to Special Summon "Copybokkle" (???/0) and change its name to that of the targeted monster. As another "Socketroll" was Special Summoned, the effect of the first "Socketroll" lets Roboppy Special Summon a third "Socketroll" from his Deck. He uses a "Socketroll" and "Copybokkle" treated as "Socketroll" to Link Summon "Appliancer Celtopus" (0/LINK-2/↙↓) to the Extra Monster Zone. He then uses the last "Socketroll" to Link Summon "Appliancer Propelion" (1200/LINK-1/↑). As Roboppy Link Summoned an "Appliancer" Link Monster, the second effect of "Electrilyrical World" lets him add 1 "Appliancer" from his GY to his hand. He returns "Socketroll". Roboppy activates "Appliancer Reuse", letting him Special Summon a Level 4 or lower "Appliancer" monster from his GY, at the cost of shuffling it into the Deck when it leaves the field. He Special Summons "Socketroll", then uses it to Link Summon "Appliancer Vacculephant" (1000/LINK-1/↗). Roboppy sets 2 cards.
