This is when Kensei arrives at the battle scene and of course doesn't recognise Akotei (Akotei lived way before his time) but after witnessing the 3 Great Daimyō and 2 Kamishikara go down, he instantly uses the Tochi Mode. Kensei actually has a chance in defeating him as they are quite even in power. Then, Akotei steals the Bushido Treasure from Akina (The Yumi) and becomes much stronger. Kensei is losing so this time, he releases much more Seizan and the fighting spirit actually covers him instead of just being a ghost in his back. (This is called the Full Tochi Seizan Mode)

Kensei becomes much stronger and is able to keep up with Akotei in the fight. Later though, Akotei also uses the Full Tochi Seizan Mode because if you really think about it... he's fucking Akotei. Akotei is stronger than Kensei again... and this time uses so much of his power, he traps Kensei in the ground. Kensei is stuck so he goes unconscious. There he meets Raijin the God Samurai of Lightning and befriends him. Kensei wakes up and awakens a new source of power and dubs it 'Bolt Action Raijin Mode'.

Kensei fucking sues Akotei's ass and plays around with him... (No homo). But then, Akotei uses godly powers and uses the Shinjitsu Mark (The truth mark) which allows you to do teleportation, fly, telepathy and much more. This time Akotei finally destroys Kensei but decides to spare him and searches for Gaiden. His arch nemesis.

Meanwhile, Seijūro meets his sister again, Takara. Takara states that she isn't herself as she has been reincarnated after her death which is unknown and how she is being controlled by Akechi. Two have a fight on which Takara is winning after she awakens her Honoured Hadāmaku: Kagami Mark of Passion. She continues to beat the shit out of Seijūro even though he has the Kagami Mark of Grace.

Later on, Takara uses her own Tochi named the Devil Falcon, Akukon. With this, Takara becomes much stronger and again, continues to beat the shit out of Seijūro. Seijūro still has access to the Chaotic Sealed Saisei Seizan but that doesn't really help him whatsoever. Luckily, Seijūro awakens his own Tochi named the Devil Eagle, Akushi. Now, they are evenly matched and the fight goes back and forth.

During the climax of their battle, Takara with Akechi's power awakens an incomplete version of the Shinjitsu Mark. Seeing as it is too much for her, Takara says her final words before committing seppuku (killing yourself) in front of Seijūro. Much to his anger.

Meanwhile, Akindo meets Akechi. Akindo quickly states that he is the reason for this mess he created and wants to kill him much to Akechi's laughter. During this fight, Akechi awakens so much power and destroys Akindo in the fight. Akindo then uses his Tochi which is the Seizan Kage and with this is pretty much even with Akechi if not stronger. Akechi later says "I was working for Akotei during our era, he said that I was his favourite servant... I hated it... I wanted to be free... so I organised and army named the 'Saisei Gang' and together we assassinated Akotei and later killed him. Akotei being reincarnated probably wants to find me...you know, you are very smart... Hattorī Hando..." and after commits seppuku. After listening to what he was saying, Akindo goes and finds Akotei.

Later on, Kensei, Momoko, Keiji and Keiko reunite with Seijūro and with that, the team is reunited and they all go and find Akotei. Akotei after dealing with the 3 Great Daimyō arrives at the main battlefield with the Western Allianced Army facing him including the Reborn Gaiden, Hikaru, Tagosaku, Akindo, Kensei, Momoko, Keiko, Seijūro, Keiji and others.

They all attempts to fight Akotei but Akotei uses his Shinjitsu Mark and pretty much handles them by himself because if you REALLY think about it... he's fucking Akotei. Takeru Heiwa uses the 5th Extremeties Breeze and becomes much stronger than Akotei dealing so much damage to him.

Gaiden and Hikaru later use the Armoured Mode (Using your Tochi as armour) and become much stronger than Akotei even with Kensei, Tagosaku and Seijūro using it as well.

Akotei pretty much pissed at this uses his Shinjitsu Mark to find all 7 Bushido Treasure Weapons. After a while, he collects all seven and obtains godly powers. With this, he's pretty much unstoppable. At first he plays around with every single samurai on the battle field and later erases every single reincarnated character including Gaiden and Hikaru.

Which means that it is only Kensei and Seijūro to finish off Ako... nope, Kensei and Seijūro die. Shocking everyone and also leaving everyone lose confidence and self esteem. With this, Akotei almost kills the Western Allianced Army.

Meanwhile, being the main characters, Kensei and Seijūro are in another dimension/world. They both meet the Shurui Twins, Megami Shurui and Seinaru Shurui said to be the creators of the God Samurai's and the creator of the Bushido Treasure. Seinaru stops time in the real world so that they can preform a ritual in giving Kensei and Seijūro godly powers.

Back on earth, time continues and Akotei is just about ready to kill Momoko but luckily, Kensei comes in and saves her. Kensei arrives with his three new swords, one Wakizashi, one Katana and one Nodachi (Long Sword). Seijūro also arrives and together they awaken their godly powers.

Kensei Kibo with his Golden Bushido Raijin transformation with his skin going gold and him resembling Raijin who is an Oni (Demon) much more and possessing three swords. Seijūro however skin turns olive green with dark green spiky hair. His eyes are black with green pupils and he grows wings himself.

Akotei becomes much more angrier and instead releases his full power and erases everyone apart from Kensei, Seijūro, Momoko and Keiko. Momoko and Keiko have to sit in the background (Cuz they weak as fuck) while Kensei and Seijūro put in the work. Moving forward, Kensei, Seijūro, Momoko and Keiko successfully kill Akotei with the BIG ass Tochi sword.

Now, Kensei and Seijūro preform the ritual to ressurect everyone who has been erased. Including the Reincarnations. Seijūro and Takara have one final emotional moment, Gaiden uses his POWERFUL speeches on Akotei changing him into a good guy and Kensei reunites with his family. And everyone lived happily every after... the end... oh yeah, all the reincarnations perish eventually.

AND THAT IS THE END OF BUSHIDO

Wait.. Season 4 with Kensei's children?
