its not that country that summon and sell ppl.  its another that its actually Neutral country that its hidding tecnology.  this is one of the top 3 countries in the world.  ( actually just a marrionette country of some final boss later in the novell.) .  anyway as i said before.  that country its not the one that has been summoning.  thats why many of the students who are being treated well. and also have same japanese ppl there who already have a life.  feel confortable.

Im honestly confused why Yui feels so comfortable with fighting for that country. Wasn her entire plot point her trying to find Yuuta because he was pretty much sold as a SLAVE by that country right in front of all of them? Did she not think anything at all about what she is being made to do (kill people), and what kind of country shes working for that summons people without their consent and then enslaves them or turns them into living weapons? And she doesn even show one bit of doubt on the stuff she gets told by the people of that country. Its like her character is so one dimensional that she only exists to create that You killed my friend! drama. This story falls apart where its entire drama matters the most amd falls flat on its face because the character lacks normal human reaction IMO.

yeah now they quit with the contract... that dumb ass team can eat all the reward and die later, that reaction was gold
