Zekkai is the coolest attack. You just run through and obilerate anything. Although, I wonder if the Zekkai technique was included in the Legitimate Heir scrolls. Probably not, because if it was, Shigemori would have been pissed off that Masamori would have been able to do it. Since if it was a Legitimate Heir technique, Masamori should not have known about the attack.
That is what I liked about Kekkaishi. Every Kekkaishi has the power to rival each other.
Sure, in the beginning, Masamori could easily beat Yoshimori and Toshimori in a kekkai battle. But once they reach adulthood, it will be a much more even playing field. Kinda of like in real life. You might be 15 years old and be much stronger than your 10 year old brother. But once your 10 year old brother reaches adulthood, you won't be able to kick his butt anymore. Sure you might still be stronger but only by a little bit.
That is true. Toshimori could have metsu some training dummies or something. And yeah. Toshimori didn't have much confidence in his Kekkai skills. Poor kid. I think that is why he never trained earlier.
Look at it from his point of view. Your older brother is the Legitimate Heir and he will be the one to inherit all the Kekkaishi goodness. Toshimori can train and be a great Kekkaishi too, but it is pointless. He is not going to get be a Kekkaishi as a career. It would be better for him to focus on something that he would be allowed to do.
In a way, that happened with Sumiko. Sumiko trained all her life to be a great Kekkaishi. She became extremely powerful, maybe even more than the 21st Heads. I wouldn't be surprised if she was the strongest Kekkaishi. Anyway, because she is not the Legitimate Heir, she can't be a Kekkaishi as a career. Once Yoshimori was born, Shigemori probably told her "Ok, you don't have to be a Kekkaishi anymore. Retire and provide for your family." Because Sumiko trained all her life as a Kekkaishi, she never picked up any other skills. She never learned to cook, clean, or do anything else. All she knew was how to be a Kekkaishi.
In this sense, it is perfectly smart for Toshimori to take his time and train his Kekkai abilites in his own pace.
I do think of Kekkaishi like sports in a way. There are some soccer players that are better than other soccer players just because. There is no real reason. They are just better. Kinda like Tokiko and Shigemori. Masamori said that Tokiko was the most powerful Kekkaishi during the 21st Head generation. He never gave a reason. So, I assume that Tokiko is a better Kekkaishi than Shigemori just because. There is no hidden underlying secret why she is better. Tokiko just is better than Shigemori. Simple as that.
But I don't think Tokiko is better in the sense that She would easily defeat Shigemori in a Kekkai battle. She would eventually win, I suppose, but it would be a close match.
Come to think of it, we never saw Kekkaishis fight other Kekkaishis. How would Kekkaishis duke it out? They can't Metsu each other. That would be one shot, dead into a million pieces. The battles are probably some sort of tests. First Kekkaishi to Metsu this ayakashi wins. First Kekkaishi to catch the ayakashi without performing Metsu wins. Test of skills, I suppose.
Tokimori did say that there used to be other families. Sumimuras make blue Kekkai. Yukimuras make green Kekkai. Could there have been other families that made Red Kekkai? Maybe Yellow, Orange, Purple, Pink, Brown Kekkai?
There would have also been more Legitimate Heirs back then. Sumimuras have the Houin Mark on the right hand. Yukimuras on the left boob for girls and pec for guys. Where would the Houin Mark go on the other families? The leg? The Eye, the tongue. the back, the shoulder, the stomach?
Chushinmaru must have been able to see into the future of the babies. At the end of the day, it seemed that the Houin Mark appeared on people who would be the most "fun" for Chushinmaru. Yoshimori's recklessness, huge power, and fighting spirit were cool and fun. I guess Chushinmaru saw that Masamori and Toshimori would be boring or something. Same thing with Sumiko and Tokio.
I kinda wish Toshimori had a bigger role. I would have understood if he didn't have any powers, but he did. Toshimori could have done more. But then, I suppose that would have made him a 3rd wheel. Toshi could have gone to Karasumori with Yoshi and Tokine, but he would have been useless. Even if he did train until he was 9, he still would have been weaker than Yoshi and Tokine. He would have needed rescueing all the time. He might have become the Scrappy Doo. Toshi going to fight somebody, but then Yoshi holding him back and saying the monster is too strong. Toshi would have probably gotten in the way of the YoshixTokine moments. I suppose that is why Yellow Tanabe never made Toshi go with Yoshi and Tokine. He would have just been in the way.
Still, he could have done something a little more. Maybe, the house got attacked even worse than when Shion's goons attacked. Maybe Shigemori gets knocked out by surprise or he was away somewhere. Toshi could have had a cool little battle to protect his dad and possibly Tokine's mom.
That would have been cool to see.
