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)

A chapter showing nothing. They working hard to show 'something', then people are pissed a half hour latter when Shirone was hard working to last for 10 minutes doing something. Something something something. To even call this a cliff hanger is hard because of lack of knowledge about what is happening in the first place.

Blackmail is impossible. You can't reveal someone is a "evil spirit" without revealing yourself.

Also RL references wouldn't work anyway as the game people clearly don't know shit about the real world or even know there is one.

So it's less someone acting or knowing something someone from the real world would know rather than not acting like people expect and being too ignorant of things.

Also people don't really socialize between other parties inside the dungeon either. Two barbarians keeping to themselves would not be at all odd.

Finally again there is information Jandel could ask for and give that would have benefited them both, even if Jandel doesn't party with em.  For one asking how xe came into the game world, how much xe had played of the game or even if xe had ever played the game. On the flip side Jandel could inform em that people are looking to kill barbarians for their hearts which have financial value, and anything about the game xe might not know if xe hadn't played it or played it much. Like about the need to pay the death tax etc. Other hints for how to survive.

Also enough of "coward" I'd probably be very frightened too. Fear makes sense here. Obviously that fear needs to be overcome just to survive, but let's not judge em too harshly with words like "coward"

Also if anything Jandel is also a "coward" turning down a chance to learn more to potentially go home etc. as well as help someone out more, because of some very very slight theoretical risk.

"Pretending to be" doesn't matter, what matters is how they behave

So when you attack the ground it disappears rather than is dug it seems
