Her reasoning was that he was a land god who needed to be healed.

It destroys a large part of the school and attacks the town before she finally steps in.

She lets it free to rampage and become stronger. In one instance she drags a dragon to Karasumori with no warning. She also attempts to do good but doesn't think about things through. It's stated that she's the most power of the Kekkaishi and that's true. Her father even states that he actually enjoys Shuju more than her. Her husband Shuju tells her that he's finally had enough of her ways and doesn't want to see her again. One of the best scenes in the manga comes when the family realizes that she hasn't actually been visiting home but sending shikigami. In fact she's a sociopath and flat out admits it. It's true he does a lot of shady things in the manga but he does it all for the greater good. His grandfather suspects that he's doing things that would bring dishonor to the family's name if it was discovered. He's always viewed as the perfect son to everyone except his family in the later arcs. Masamori is shown to be the perfect son in the first arc and Yoshimori almost hates him for this. The two it does the most to expand on are Masamori and Sumiko, Yoshimori's brother and mother. The manga does a lot to expand on characters. The landscapes are usually drawn softly so it's a nice contrast to the sharpness of the fights. Lastly the manga features a lot of shots of landscapes and that's also a place it excels. The manga also has incredibly detailed fights. I understand that baking cakes is Yoshimori's hobby but it's okay to slack off on cakes.

I needed to point out the cakes because they are drawn in a ton of detail. The cakes are incredibly detailed and drawn. Where the art excels is the images of cakes. The art is good but there are some sloppy scenes. The mangaka actually has little breakdowns after some arcs where she admits she didn't expect the series to run all the way through the first arc. The anime didn't leave anything out but the manga did a lot of rapidly expanding the universe after the first arc. In one he fights his mentor who has turned to the dark side. The manga also spends much more time on Masamori and The Night Troop. I'm trying to keep it spoiler free because small spoilers will blow open entire plot points in this series. While the story may seem stuck in place I assure you that they eventually move to other places. The anime made it seem as Yoshimori was the main character but Tokine actually gets a few arcs to her development as well. The story follows Yoshimori and Tokine the youngest generation of Kekkaishi as they protect the land of Karasumori from threats.
