Well, here's the thing:
Soul Eater started out as a मांगा series. The ऐनीमे is an adaptation of that manga. For the first 34 episodes या so, the ऐनीमे was pretty damn faithful to the manga. Of course, the ऐनीमे studio noticed a bit beforehand that they were running out of मांगा to adapt, and they only had a 51-episode budget, so they did the best possible choice: they diverged from the original manga's plot and took their own spin on the duration of the season, tying up as many of the remaining plot points as they could for a premature ending. If आप ask me, they picked a wise point in the story to विभाजित करें, विभक्त करें off from the anime. Otherwise they'd have to add और plot points that would risk being unresolved in the end.
As we speak, the मांगा is still being released, with no foreseeable end currently in sight. The characters and a few major events are all developed quite differently. If आप can find any copies, I definitely recommend आप read them.
Now, as for the सेकंड season:
The एनीमेशन studio responsible for producing the original ऐनीमे is "Bones", the same studio that brought us Fullmetal Alchemist, which was a very loose adaptation that ends up being developed differently has requested द्वारा the creator of the series. Now बोन्स has made Fullmetal Alchemist: Brotherhood, a new adaptation that follows the original मांगा और closely.
What does this have to do with Soul Eater, आप might ask?
Well, word has it that the producers of the ऐनीमे are considering waiting for the Soul Eater मांगा to play out for a bit longer. Maybe when it's close to finished, then a new season, या perhaps और appropriately, a whole new Soul Eater ऐनीमे will be produced.
It's just a rumor best taken with a pinch of salt, and आप can find it in this video:
