I wonder if unique skills are associated with bosses. The mc was killed by a minotaur, and got an unique skill, the girl knew about the werewolf. Nao got an unique skill after helping defeat the werewolf

He has better stats, even then he spends more Points on skills

Cup breaking is a bad sign....

He seems to get a lot of enemies with blades. His first rival was the praying mantis and it came back, the female mantis. The Hercules beatle, the other Beatle, and the other Beatle... It may have been another Beatle before this guy, but I don't think it has a blade like weapon.

Not sure but some of them were based off marine life forms, and were amphibious. Well sid seems like a humanoid worm 

The little sister is contributing so little, she could be removed, and if he falls in love with one of the other girls, from the pov from the other girl, the title would still be accurate.

Well since mihara might have a crush on the mc, that makes her sister her crush's crush, and that would make the prez her crush's crush's crush, and that would make her crush, her crush's crush's crush's crush, while she's nobody's crush 

If he collapses for a day, I doubt the girl would think to grab it, right?

If they should be defeated in a certain order, you should've made them more readily available in that order.  Dozens of people already had a quest to challenge wezaemon, and they knew his when he appeared, so it would be easy to find a chance to defeat him. Lycaon could also be defeated early as it randomly appears, it could attack a guild full of pros. 

Him: I know I can't beat you....but don't interrupt meAlso him:https://i.postimg.cc/SRjc4sZF/i.png

Why swing first if you know you can't win? You're ranked 17th, you're not even in the top 10. You know he defeated someone much stronger than you, in one hit....what makes you special?

His party seems pretty big, so I'm guessing, he's the first person not to meet his standards. He probably feels it would be a slap in the face of he makes it big now,  even though he was useless when he recruited him.  He's not gonna think, if he was patient, he could've had a diamond in the rough, nope, he was holding back to embarrass him. He's gonna be unreasonably mad, when Klaus finishes, and we will see his inner monologue, explain  he's angry 

He hates the mc because of his skill. He thought of it as useless and kicked him out of the party. If he knew how strong it was, he would've taken advantage of it, to make him a farming slave or he would've killed him. He only kicked him out because he thought he was a burden. He's hindering, because he doesn't want to be proven wrong. How could someone he took in and gotten rid of, actually be useful, if he was kicked out of his party?  Since he wasted him time on him, he doesn't deserve to have a career as a adventurer

In her defense she was tortured by different monsters and killed right when she believed she about to be saved. While the mc didn't really have any hope, and usually faced with a fatal blow and finished or a single blow. She faced a stampede, being trampled and monster biting an eating her, then was met with a fatal blow. Being eaten alive seems like it would break a person quickly. Even when the mc was split in half by the minotaur he seemed like he was more in shock and confused, rather than in pain

In the earlier chapters when he was a baby to four. He spoke to her when he was a baby, and told her to keep it a secret. She was close to him in the previous life. I believe when he was struggling, she supported him, and I believe she died. The last part might've been mixed up with another manga, but it's been a while.

Might gai when he told kisame don't move a finger

I'm glad they didn't forget about her. The mc seemed close to her in his past life, and he did treat her like a sibling the brief time she was shown. Just hope it's not because she's gonna be target by some suicidal fool trying to get back at the mc

He probably got close to her due to her father and believes that as long as he has the father's approval, she's as good as his, so he trying to keep her bound to her father

So Janice, one of the strongest players that the mc met during a mission, is being chased because he refuses to reach the max level and end the contract. Someone made a whole village go crazy and massacre each other, until one survivor was left, and they made her and Janice live together until they fell in love with each other. When they lived together so long they couldn't live without each other, he ordered the dragon slayer to kill the girl

Some information is being left out.  It has many possibilities. 1. That was Janice's original world, and a player wanted to toy with people, and the soul company brought Janice in as a player, as they did say this isn't the only dimension they work in. 2. It could mean Janice experienced it all with empathy sharing, but the person he took over, took his body back and killed the girl, and Janice is going through what the mc did, with sapiel. 3. The same as the first, just without a player involvement, just a horrible person who could brainwash people. 
Really depends on whether the third party was a player or not, and whether or not he influenced Janice directly or the person he was controlling.
But Janice is trying to understand the method of bringing someone out into the real world, and the company doesn't like that. 

Janice was the overpowered player with I believe black hair the mc met when he was like prince or leader of the gated city. The people were starving and to wait for back up before the monster attack or something like that, he met the dragon slayer outside the city and they made some type of agree. It was like his third mission.
