The Japanese past tense is ました. ます refers to what will happen (which is generally correct).

Eat (eat)

Eat (I eat)

As for your "でぁる", I don't quite understand the meaning of this question.

でぁる is usually "yes" in Chinese.

Natsume Sosky's most famous sentence

We are cats (we are cats)

If you add からして to でぁるからして.

It means it's because ~ that's why ~

このはこぅでぁるからしてこぅなった.

This is why it's like this.
