I liked that it wasn't some after image but a actual different body.

I don't recall for sure, I think it was said in a earlier chapter. I'm thinking perhaps a car accident?

Not at all, There has been a consistent pattern of a teen joining the group with a power or getting a power/means of contributing to combat. Even the fat person with the obsession and misunderstandings about lewd jokes regarding the golden ball, has the power to use the mano-machines way better than anyone else, especially for combat purposes. If she joins the group, it's almost certain xe will get some kind of power. And with that bit regarding liking vampires and thinking glasses was a vampire, it seems like xe will join the group eventually. It took Fatty awhile so it will probably take her awhile to join as well.

The power will probably be a singing power.

I liked this chapter, but I'm really sick of the combat. 

Could be a translation issue. MC saying xe is turning into a ghost like spirit, not the kind of being that can be summoned.  None of the summoned beings look like or seem to think like, humans.

And if summoning was raising the souls of the dead to enslave them to your will, AKA ghosts, OMG that would be a dark turn in the world building.

Who is Mac?

Not sure ghosts and spirits are the same thing in this comic

I cheer em on. Fight for what you believe in. Nice character fleshing too. 

These seem to be English words but I do not discern any meaning to them.

How dare you not listen to my complete tirade then save my life!

https://i.postimg.cc/nLj28NN8/i.jpg Could this be referring to mom? I suppose not, just the wording...

Did you forget Lilly being used as a tank against the spiders because Lilly can't die as long xe has mana? Or at least very hard for Lily to die, that fiery aura protects xer.

Note I did not say "Lilly can't die." the phrase "as long as xe has mana" is crucial here.  The mana's used up to block the damage. Like the mana is another health bar.

Why "unnamed"?

gender neutral pronoun.

What is "T"?

How is it that he couldn't find a single real demon slayer?

Control and sense erections, so like erection bending. The one power the avatar doesn't have.

Stupid fake-out cliffhanger. It doesn't feel like anything happened in this chapter

Well Lily is immune to death as long as xe has mana or something, right.

It's not rain, it's urine. Wait... (this is a joke BTW)
