Freezing Armament! Aqua Ryukendo (氷結武装!アクアリュウケンドー! Hyōketsu Busō! Akua Ryūkendō!?) is the fourth episode of Madan Senki Ryukendo. It features the debut of the Aqua RyuKenDo.


Fire RyuKenDo defeated the advanced demon, Swordsman Tsukaima using his finishing move, Blazing Slash. At S.H.O.T.'s Base, the Madan key obtained from defeating Jamanga's armoured black tank was found to be Aqua Key by The Book of Canon of Light and began to adjust. But they don't know how to use it. On the other hand, Rin pointed out from the people in the city that the stronger RyuKenDo is, the more powerful the enemy will be. Then, the Swordsman Tsukaima who should have been defeated appeared again. The enemy has challenged the battle with its new flame slashing power!


RyuKenDo is seen fighting Swordsman Tsukaima but facing issues. GekiRyuKen advises RyuKenDo to use Fire Key to counter the heat effect of Swordsman Tsukaima. Fire RyuKenDo tries to use his finishing move, Blazing Slash to attack Swordsman Tsukaima, but some Tsukaima appears to protect Swordsman Tsukaima but is stopped. Swordsman Tsukaima is no match for Fire RyuKenDo and get defeated, with Fire RyuKenDo tried to obtain the Madan Key but is stopped by the few Tsukaima earlier. Back at Jamanga's Base, it is revealed that Swordsman Tsukaima's defeat is part of Doctor's Worm plan to obtain firepower from Fire RyuKenDo.

Rin has a conversation at S.H.O.T.'s Base with Kenji regarding demons getting stronger, but Kenji feels that if demons get stronger, all they have to do is to get stronger too. Meanwhile, Setoyama decrypted the Madan Key recovered from Doctor Worm's tank which revealed to be Aqua Key, granting the power of water. Kenji felt that Fire Key is enough and wants Fudou to take Aqua Key, but the latter rejected, resulting Kenji to accept the Aqua Key. Kenji is curious about the abilities of Aqua Key, with Setoyama suggesting putting out a burning building but will steal firefighter's job. Setoyama tries to suggest another possibility; this time will be freezing a time bomb with hostages held captive but might end up freezing the hostages together due to powerful freezing abilities. Rin interrupted the conversation, commenting that Jamanga didn't set the city on fire or set time bombs with Kenji commenting that they might soon. Amachi suggested using Aqua Key for filling a hot bath, with Komachi added bath must be entered when hot, causing Kenji to ask around why is Komachi at S.H.O.T.'s Base, making her disappear immediately.

Fudou transforms into RyuGunOu and meets Doctor Worm in the woods at Akebono Temple. Doctor Worm commented that the Madan Warriors involved with the Kanon without knowing anything and questioning them him for getting in Jamanga's way. Doctor Worm explained that they only wanted Minus Energy (Sadness, Pain and Fear) obtained from humans. Due to failure in negotiation with RyuGunOu, Doctor Worm summoned an evolved form of Fire Swordsman Tsukaima to fight him. Fire Swordsman Tsukaima launches an attack at RyuGunOu, causing his left shoulder pad to get burned. Kenji received a phone call from Rin asking him to aid RyuGunOu fighting Fire Swordsman Tsukaima at Akebono Temple. After asking for directions to Akebono Temple from a shop owner selling croquette, Kenji reaches the location but is shocked by the long staircases leading to the woods. Kenji transforms into RyuKenDo.

RyuGunOu got his right shoulder pad burned by Fire Swordsman Tsukaima and saved by RyuKenDo when Fire Swordsman Tsukaima tries to launch an attack. RyuKenDo felt that Fire Swordsman Tsukaima looks familiar and guess that it is the guy he eliminated in the morning. RyuGunOu warned RyuKenDo on Fire Swordsman Tsukaima obtaining the power of fire from Fire RyuKenDo. RyuKenDo changes into Fire RyuKenDo as normal mode cannot fight against Fire Swordsman Tsukaima for long. After transforming, Fire RyuKenDo lost sight of Fire Swordsman Tsukaima, which revealed that Fire Swordsman Tsukaima is hiding in the ground to land a sneak attack but is blocked immediately by Fire RyuKenDo. Fire RyuKenDo resumes his fight with Fire Swordsman Tsukaima, with the city set alight by falling fireballs as sky turn dark.

Amachi asking Setoyama the status of Aqua Key as Akebono City is on fire but got a reply that it is not ready yet. Fire Swordsman Tsukaima manages to block a double attack launched by RyuKenDo and RyuGunOu together as the fight continues. Amachi orders Setoyama to send the Aqua Key to RyuKenDo after download completed on the key. At last, Fire RyuKenDo receives the Aqua Key and changes into Aqua RyuKenDo. Aqua RyuKenDo cools down Fire Swordsman Tsukaima's sword with its freezing ability and uses his finishing move, Freezing Slash to defeat Fire Swordsman Tsukaima, obtaining a Madan Key as a result. Meanwhile, Akebono city started snowing, putting out the fires on the way.
