If Ciel gets his soul eaten after Sebastian fights the ángel and avenges Ciel's parents. THen why is there a segundo season o an episode about a play?

Aaaah, but it is not game over, Ciel's soul does not get eaten, did tu know that when Ash/ Angela fought with Sebastian, his arm was cut off and his contract with Ciel was off for about a few minutes, enough time for (spoiler) Alois to take it. Thus, Ciel is souless, the beggining season 2 is based on how Sebastian get his soul back.

i wounderd that a first too but about 1/4 into the segundo season it says that ciel doesnt get his soul eaten if u watch it u will understand (and of course ciel avoids being eaten in the segundo season too)

what if he didn't eat his soul and just gave him a kiss o just did something else because in the segundo season i have heard something amazing happens.

The episode about the play is just an OVA. There is a season two because another demon butler had ciel's soul before sebastian could eat it. therefore losing his memory

well tu see ciel does not get his soul eaten.

everything is explained in season two. blame Claude for Ciel not dying.

Sebastian didn't want to take Ciel so he didn't and also he felt that Angela want the one who set the fuego so Ciel still needed to still seek his revenge

I don't even know...

Season 2 is not a canon, the studio o whatsoever productions of that anime wants to make fillers. There is no such proof even in manga that Ciel's soul gets eaten por Sebastian. Season 1 half of the episodes 16 and above are not canon.
Trancy Arc is just a filler, fred Abberline twin is a filler.

because its mostrar us what he looks like now and that he is going to die
