Giant Mecha Soldier of Karakuri Castle
カラクリ城のメカ巨兵 (Karakuri-jō no Meka Kyohei)


The Straw Hats visit an island, known as Mecha Island, where a fisherman sings an old folk song about a Golden Crown. Searching for that mysterious treasure, they find a hidden entrance into the island. The island’s leader, Ratchet, impressed with the find and in search of the Golden Crown himself, invites the crew to join him in his search and the crew along with Ratchet and his henchmen enter the cave. As it turns out, the island’s true form is that of a giant turtle. Ratchet, who had known this all along, uses his mechanical castle to take control of the turtle wishing to use it to take over the world. Now the Straw Hats have to stop not only Ratchet but also the helpless turtle, from crashing into a nearby island.

TL;DR Review

The Giant Mechanical Soldier of Karakuri Castle movie relies on more jokes than the previous movies since the villains are rather weak here. The Straw Hats crew are still made up of Luffy, Nami, Sanji, Usopp, Robin, Chopper, and Zoro. The movie took place between season 8 and 9 from the TV. Not only are there more jokes in this movie, but it is also more sexualized. Within the first 5 minutes of the movie, I swear Nami breasts must have jiggled 15 times.

I believe this is the first time we got a clue of Luffy second gear from this movie. There was an attack that compresses Luffy in the same way when he activates second gear. He seems puzzled at his increase in power. The villain was underwhelming to say the lease. If you don’t mind reading a lot of dialogs with more jokes than combat, then you may enjoy this movie.

This movie is only recommended for One Piece fan. The anime contains strong graphic violence and moderate suggestive themes/dialogs.

Spriggan Movie Review

Spriggan was initially released as Striker in the North American English translation, as it is the English translation of the word “Spriggan” from Cornish.

Many years ago, an ancient civilization known for their advanced technology once ruled Earth, but were destroyed in the end by their misuse. So, they left messages for later generations in the form of indestructible message plates written in ancient Hebrew, informing them that if they could not find a good use for their creations, they should be destroyed. Various paramilitaries, national armies, and armed private forces began to secretly search for these “mysterious artifacts” in order to be used for their own good and against their enemies. The ARCAM Corporation and their military arm, the ARCAM Private Army, can stop these forces from destroying themselves with their elite secret agents known as Spriggans (or Strikers). The film in an adaptation of the Noah’s Ark story.

Pirate King Gol D.Roger
"Destiny… fate… dreams… These unstoppable ideals are held deep in the heart of man. As long as there are people who seek freedom in this life, these things will not vanish from the earth."
"Men who can't wipe away the tears from women's eyes aren't real men."
Monkey D. Luffy
"I don't care what you want, whether you want to live or to die!!! But whatever you decide, say it while you're with us!!!"
"There comes a time when a man has to stand and fight. That time is when his friends or dreams are laughed at.”
Pirate King Gol D.Roger
"Inherited Will, The Destiny of the Age, and The Dreams of the People. As long as people continue to pursue the meaning of Freedom, these things will never cease to be!"
"You can't bring back what you've lost, think about what you have now!"
Dr. Hiluluk
"When do you think people die? When they are shot through the heart by the bullet of a pistol? No. When they are ravaged by an incurable disease? No. When they drink a soup made from a poisonous mushroom!? No! It’s when… they are forgotten.”
Nico Robin
"Fools who don't respect the past are doomed to repeat it.”
Red Haired Shanks
"By experiencing both victory and defeat, running away and shedding tears, a man will become a man. It's okay to cry, but you have to move on.”
"There comes a time when a man has to stand and fight. That time is when his friends or dreams are laughed at.”

"The Black Leg" Zeff
"No matter how many hundreds of weapons or armor one is equipped with, they are no match for that "one special spear" that comes from your guts.”

Monkey D.Luffy
"Hero? No! We're pirates! I love heroes but I don't wanna be one! Do you know what heroes are? Say there is a chunk of meat. Pirates will have a banquet and eat it but heroes will share it with other people. I want all the meat!”
Donquixote Doflamingo
Pirates are evil? The Marines are righteous? These terms have always changed throughout the course of history! Kids who have never seen peace and kids who have never seen war have different values! Those who stand at the top determine what's wrong and what's right! This very place is neutral ground! Justice will prevail, you say? But of course, it will! Whoever wins this war becomes justice!"
Eiichiro Oda
"Whether we wound or are wounded, the blood that flows is red.”
"If I were to take even one step back right now, I get the feeling that I'd never be able to return back to where I'm standing right now.”
