When you've read so many plots about 'good friends' betraying you for the most stupid reasons.
You start being influenced and believe every person is shit. O wait, that's just fact.
Definitely an embarrassing 'lets become S-rank adventurers' NEXT PAGE 'we made it to S-rank, now we hardly die!' 2 pages later 'you take 25% of the loot, you're just leeching our money! Go be executed'
Like based on this, 25% is the cheapest infinite life cheat I've ever seen. I REALLY want author to just toss in 2/3 of them dying days later due to some monster.
