Have you considered this ?
The anime ended pretty early on. How many episodes would be necessary to cover the content from there to here, or would they skip parts, and how would they choose which parts to skip ?
Let's imagine they don't skip anything and give weekly episodes. I have no memory of the actual amount of chapters covered in the anime, but it would probably take atleast one full year's worth of episodes, 52 to get anywhere close.
And they just don't start those types of animes any more, very few anime are in the hundreds of episodes, and they would've been going on for quite some time, but I have no memory of any such being started in the last 10 years or so, but I could be wrong.
