- For information on Ryujinmaru, check the Dragon Deities page.
A fourth-grader who is brought over to Soukaizan in order to become its savior, and is the title main protagonist and hero of the series.
- All-Loving Hero: Wataru's a boy who genuinely loves all the people who he befriends. Which makes every moment of friendship betrayal towards him very tough to watch.
- Badass Cape / Bling of War: Wataru will wear variants of these from Ryujinmaru's various super modes.
- The Chosen One: He was chosen to become the savior of Soukaizan.
- Got Me Doing It: Some of Himiko's wacky nicknames for people would grow on Wataru. Particularly, "Yamahiko."
- Jumped at the Call: In the first series. The second series, however, has him a little more reluctant to go since for one, he was back home for only one week from his journey in the first series, and two, he wasn't aware Soukaizan ticks their clocks faster than his world's, and a big part of it is due to Ryujinmaru not having the awareness to explain it to him.
- Lovable Jock: Wataru is an academically average kid whose talents lie in sports. One of the reasons the Dragon God chose Wataru to be their world's savior was by checking the amount of awards he received from sports competitions that was laid out in his bedroom.
- Kid Hero: An elementary school student in all series.
- Wholesome Crossdresser: He can easily pass as an extremely adorable girl when under disguise in W1 ep.28; complete with natural Proper Lady gestures.
The 13th successor of the Shinobibe clan with a seemingly endless amount of energy, she joins Wataru on his journey starting from the 1st floor of Soukaizan since the original series.
- Bag of Holding: Predominately used in Wataru 2, Himiko has one with her at all times. Keeping all of her utilities, weapons, food, medicine, her favorite toys, and all kinds of bizarre stuff in her small pouch.
- Big Eater: The food vacuum cleaner of the entire team. She can down all ginormous foods in front of her in less than an eye-blink.
- Catchphrase: "Banzai! Banzai!" through the first series. By the second series, she decreases the "banzai" usage in favor of a new sentence—"(Insert name here), you're so awesome! (Insert name here)'s Number 1!"
- Characterization Marches On: In the first series, Himiko was just your regular, good-looking Genki Girl, but as the second series rolled in, her character really vamped up by setting her free from her "bishoujo-styled line art", and redesigned her with looser animation so that she can be much more creatively expressive. And wacked up she did!
- Children Are Innocent: The reason why she can bend heaven and hell to any direction as she pleases using just her personality and pure energy is really because she literally doesn't know what logic is, and doesnt even care how logic should work.
- Cuddle Bug: Himiko loves to jump on her friends whom she hasn't seen for a long time. Every one of them.
- Eyes Always Shut: Himiko's predominate trait that was developed, and solidified since Wataru 2.
- Genki Girl / Plucky Girl: She's basically a girl installed with one hell of a battery pack that never runs out of juice. And when the situation calls for it, she will not hesitate in pulling moments of Big Damn Heroes in her usual hyper smile, or with a sure damn serious face.
- Living Emotional Crutch: Of Toraoh.
- Medium Awareness: Himiko is keen on their world's Strictly Formula system and uses them to her absolute advantage.
- When competing ninjutsus with Chuta Oniwaban of Seikaizan, Chuta shows off by transforming himself into a cool dragon, but then Himiko one ups him by transforming herself as Ryujinmaru, and forced smack Chuta as "the background dragon of Ryujinmaru;" you know, the dragon in all of Ryujinmaru's Dynamic Entry sequences.
- Morality Pet: Of Kurama.
- New Powers as the Plot Demands: Being a Child Prodigy kunoichi gives her the all-time advantage of pulling off all kinds ninjutsus that will blow your sense of logic away; and was made even better with official submitted ideas from children viewers.
- The Nicknamer: Himiko is the girl who gives everyone she meets all sorts of wacky names, mainly for herself to remember by.
- O.O.C. Is Serious Business: Due to being an extremely Genki Girl, she never loses her smile, even when she should be scared.
- Therefore, do not ever, ever, bully her friends, or she will give you her serious face. And just her serious face alone would bring guilt to all who has a heart.
- Kurama and Toraoh's death were the only times she cried in the first series, with Toraoh's case being the only time she showed furious anger.
- For her Hidden Purpose Test in the middle of Wataru 2, she broke down in tears after realizing shes all alone. For her test, she has to understand that the things she felt to be fun will not give her long-term happiness, but to learn to appreciate she has family and friends who will be there to comfort her if she's ever sad, and will provide the love to make her truly happy. And it's her future self that teaches her that.
- Perpetual Smiler: The reason why she's so full of energy, and always looking for fun, is that she likes it when people compliments her for indulging herself with the things that she likes to do.
- Pokémon Speak: Before Pokemon was ever born, Himiko has already used this as a spell to summon whatever ninjitsu she has:"Himikomikomiko Himikomiko!" (Flying flowers and stars included.)
- Speaks Fluent Animal
- Too Kinky to Torture: Let's just boil them all down in saying Himiko "honestly believe she was having play time with her so-called, enemies." And by "enemies," she calls them "friends."
- Young and in Charge: She is a 7-year-old kunoichi who is appointed as the 13th generation leader of her clan.
A Master Swordsman of Yagyu Shibaraku style whom Wataru encountered on the 1st floor of Soukaizan since the original series, he decides to take the boy in as his student, accompanying him on his journey.
- Affectionate Nickname: Between him and his Mashin, he calls Senjinmaru as "Sen-chan," while himself as "Shiba-chan."
- Art Shift: Whenever Shibaraku wants to get romantically serious, whether its to impress women or to fulfill a philosophy, hell turn his face as Hunk as he can get.
- Brainwashed and Crazy: In the middle of Wataru 2, Shibaraku went out to protect Wataru by taking a brain-washing arrow and became one of Dowarudar's strongest subordinates through the final arcs.
- Butt-Monkey: If one member of the group is going to suffer for comedy, it's going to be him.
- Chivalrous Pervert: Shibaraku would not miss a single chance to buff up his "hunkness" to ogle all the pretty ladies that he meets. But he'll (sadly) back out if the ladies were already taken.
- Dual Wielding: Uses two katanas when he fights.
- Goroawase Number: To reach Senjinmaru, he has to dial "1000-10-0", a literal Pun on the Mashin's name.
- Meaningful Name / Verbal Tic: Being a man with the given name of "Shibaraku (...a while/temporarily halt)," he would blunder "give (whatever) a while" whenever opportunities calls for it.
- His Mashin certainly needs a whole lot of whiles to arrive for battle that's for sure.
- Running Gag: Shibaraku can only summon his Mashin, Senjinmaru by a giving it a paid call from the nearest local Phone Booth he could find. Which is a real pain-in-the-ass. On bad days, Senjinmaru couldn't pickup the phone in time; worse, Senjinmaru can call sick and would arrive extremely late with only a few HP to survive.
- Another one is how he's frequently mistaken for a hippo.
- The Worf Effect: Him and Senjinmaru are overwhelmed almost all the time to show off the power of the opponents.

- Affectionate Nickname: Himiko always calls him "Tori-san" ("Mr. Bird").
- The Phoenix: Kurama and his Mashin's motif. He and Kuujinmaru were killed by Hedorona in W1 ep. 22, but he was brought back to life by the dew of the revival flowers near the end of the same episode to his original human form.
- Baleful Polymorph: He and the rest of his village are humans who were forcibly turned into bird-people by Doakudar. He's mainly working for him in order to undo that. Himiko personally thinks his bird form is cooler than his human one.
- He turns back human after regaining his life in Wataru 1, but then got turned back to his bird form during his stay at the Fourth Star in Wataru 2. Empress Seiryuhi offered to turn him back human by the end of the series, but he declined the offer, explaining his willingness to stay a bird a little bit longer for the sake of keeping Himiko happy.
- Becoming the Mask / HeelFace Turn: Kurama took on the job as an agent for Doakudar for one, being forced, and two, solely for his own benefit to turn back human without considering his fellow townsmen. As he befriends Team Wataru and slowly understood their genuine friendship with him, he became intensely remorseful; eventually learns to put his benefits behind and aid Team Wataru to atone for his misdeeds.
- Big Damn Heroes: Pulls this off when he saves Shibaraku and Genryusai from the Zan Brothers.
- Bishounen: He was originally a handsome young adult.
- Eyepatch of Power: He wears one on his left eye, but then was revealed he didn't have one when in human form, and instead, wore goggles..
- I Let Gwen Stacy Die: For his Hidden Purpose Test in the middle of Wataru 2, Kurama knew it has to be something in relation of the death of his girlfriend, Yuria. But as his test went further, he has to realize the cause of her death was by him being a selfish brat for not adhering to her plea of getting out of gang violence before something bad happens to his life. As Kurama learns to atone for his sins, he also has to understand to recognize his own feelings for Yuria to be genuine love, appreciate her effort to willingly love a scumbag such as himself, and for her to believe he has chances for redemption.
- Japanese Honorifics: Kurama in particular would refer Shibaraku as "Danna," meaning "Good Sir."
- Put on a Bus: He returns to his village after regaining his human form near the beginning of the 5th floor in the first series.
- He came back for the last few episodes of W1, bringing a new Mashin, Kuuohmaru, with him.
- Took a Level in Kindness: Kurama has become much pleasant and kind towards people by Wataru 2. Kurama is also seen to have a soft spot for Umihiko, since he can see his past self in that kid.
WARNING: The following two characters are walking spoilers who holds major plot points throughout the entire trilogy that cannot be marked. If you were to watch the show, you are bound to get spoiled by reading the contents in this folder.
Introduced as the son of the Emperor of Evil, Doakudar, Toraoh is one of the major antagonists from the first series who desires to make Himiko his bride and forms a rivalry with Wataru. By the finale of Wataru, Toraoh was purified, revealing his true identity to be of Shoryushi, the Prince of Soukaizan and son of Empress Seiryuhi.
Due to Toraoh being the product of a forced Split Personality spell, the personalities and appearances between Shoryushi and Toraoh cannot be merged together.
- Affectionate Nickname: Himiko calls Toraoh as either "Tora" or "Tora-chan", and Shoryushi as "Shu-chan."
- Alternate Identity Amnesia: Shoryushi doesn't have any recollections while he was transformed into Toraoh, even when he regained his identity and understood he now has an alternate personality, he doesn't remember he has a Mashin named Jyakomaru, nor wouldn't know the actions of what his Toraoh side would do. Toraoh on the other hand, is aware of his surroundings and his identity as Shoryushi even when Shoryushi is dominate.
- By the end of Wataru 2, Shoryushi gains the memories of Toraoh, and affirms to Wataru that no matter if he's Toraoh or Shoryushi, their friendship with Wataru will never break.
- Literal Split Personality: Before the final battle of Super, Empress Seiryuhi used her remaining life energy to separate the personalities of Toraoh and Shoryushi into individual spirits and gave them their own flesh; making them twins. After Seiryuhi's death, the two princes co-ruled Soukaizan together.
- Shapeshifting: Of a voluntarily, yet restricted transformation format. If Shoryushi sensed danger involving Team Wataru or Jyakomaru, he would unconsciously force transform to Toraoh without Toraoh's knowledge. Toraoh on the other hand, doesn't know how to transform back to Shoryushi. Once Toraoh accomplishes his mission, he would gladly go back to his mother to help him transform back into Shoryushi.
- Split-Personality Team: The two personalities acknowledges each other and knows how to work their daily routines if they ever switched in-and-out, but they don't get to talk between themselves internally. Until the finale of Super.
- Shoryushi is known to share his toy figure, Seiju with Toraoh by switching their personalities around. When Toraoh was dominate, Toraoh was the one who gave Seiju a makeover by dressing Seiju up complete with clothes, hairstyle, and carved a moon on it's forehead since Seiju was originally just a plain wood figure.
- Affably Evil: As he was introduced through W1, Toraoh was noticeably not a bad kid; just a mischievous boy who doesn't want to follow anything his dad or subordinate wanted him to do, wants to have fun, and who really wanted to possess Himiko.
- Amazon Chaser: He instantly want to possess Himiko as his wife the moment when he realized Himiko can curb-stomp him.
- Brainwashed and Crazy: Since being revealed to be Shoryushi at the end of the first installment. This indicated Doakudar was merely brainwashing him into thinking he was his son.
- Toraoh was brainwashed by the hands of antagonists once again in Super, due to injecting his "soul fragment of love" to make Seiju alive, and thus lost his sense of purpose in life.
- Cute Little Fangs: Will show them off depending on how he wears his smile.
- Redemption Earns Life: In his dying moments, he reaffirms Wataru's status as his friend, followed by his mother bringing him back to life with his true identity.
- The Rival: Towards Wataru for the first series mainly on his end of the stick due to misunderstanding Wataru's relationship with Himiko.
- The Only One Allowed to Defeat You: After finding out that Wataru is trying to defeat his father, he declares that only he is allowed to defeat Wataru.
- Parental Abandonment: Empress Seiryuhi lost her life at the finale of Super. Toraoh in particular does not take it well, for Toraoh has longed for parental affection, but does not have the luxury to do so given his circumstance.
- Warrior Prince: When it comes to which personality to take up his sword to defend his kingdom, it'll naturally goes to Toraoh. Toraoh himself couldn't agree better, as he rejected Shoryushi's offer to battle alongside him for the finale of Super, and asked Shoryushi to stay by their mother's side to protect her instead.
- What Is This Thing You Call "Love"?: Toraoh was born without the concept of love, the meaning of friendship, and social etiquette. So whenever Wataru performs something that show love and humanity, such as apologizing for wrong doings, and making amends, etc, Toraoh would question him like a little child would do.
- Royals Who Actually Do Something: Shoryushi would abide by his mother's wishes to go down to the public to aid Team Wataru and solve problems with local citizens, even in locations that are not under his kingdom's rule.
- The Wise Prince: Collected, benevolent, brave, nurturing, and kind. He is willing to go to the front lines to aid Team Wataru.
