Zuzu is surrounded by Sector Security together with Frank, Tarren and Amanda. None of them have a Duel Disk, so they cannot resist. But, Sora suddenly appears in front of them!

Featured Duel: Sora Perse and Zuzu Boyle vs. Sector Security

Three Sector Security officers surround Zuzu and the kids and each one controls a "Goyo Defender" (1000/1000) and a "Goyo Chaser" (1900/1000) in Attack Position each and have three cards in their hand each. When Zuzu and the others try to run away, a fourth Security officer blocks their way,

Security #4's turn
The Security tunes his Level 4 "Jutte Lord" with the Level 2 Tuner monster "Jutte Fighter" to Synchro Summon "Goyo Predator" (2400/1200) in Attack Position.[Notes 1]

Sora arrives and gives Zuzu a Duel Disk. Sora controls "Edge Imp Frightfuloid" (1300/1300), "Frightfur Bear" (2200/1800) and "Frightfur Leo" (2400/2000).

Sora's turn
Sora activates "Polymerization", fusing "Frightfuloid" (which is treated as "Frightfur" monster via its effect), "Bear" and "Leo" to Fusion Summon "Frightfur Chimera" (2800/2000) in Attack Position. "Chimera" attacks and destroys "Chaser" (Security #1: 4000 → 3100 LP). Sora Sets a card.

Zuzu's turn
Zuzu draws and subsequently activates "Polymerization", fusing "Mozarta the Melodious Maestra", "Canon the Melodious Diva" and "Solo the Melodious Songstress" from her hand to Fusion Summon "Bloom Prima the Melodious Choir" (1900/2000) in Attack Position. The effect of "Bloom Prima" increases its own ATK by 300 for each Fusion Material used (1900 → 2800). "Bloom Prima" attacks and destroys a "Chaser" (Security #2: 4000 → 3100 LP). "Bloom Prima" can attack twice per Battle Phase, so it attacks and destroys the last "Chaser" (Security #3: 4000 → 3100 LP).

Security #4's turn
"Predator" attacks "Bloom Prima". The Security activates the Quick-Play Spell Card "Rush Recklessly" from his hand to increase the ATK of "Predator" by 700 until the end of the turn (2400 → 3100). Sora activates his face-down "Fusion Fright Waltz", which lets him target two Fusion Monsters on the field, destroy all Special Summoned monsters with ATK equal to or less than their combined ATK, except Fusion Monsters and then inflict damage to their controllers equal to the total ATK of the two targeted monsters. Sora's hand contains "Suture Rebirth" and "Toy Vendor". Sora targets "Chimera" and "Bloom Prima" and destroys the three "Defenders" and "Predator" (Security #1: 3100 → 0 LP; Security #2: 3100 → 0 LP; Security #3: 3100 → 0 LP; Security #4: 4000 → 0 LP).
