It's the dumb slice of life manga you didn't know you needed and the best slice of life manga you haven't heard of.
Yugami-kun doesn't have any friends. I'm sure most of us here have gone trough a period where we were a bit outcast in some way. So I'm sure all of you had the same reaction as me when reading the title -> "Sounds a bit relatable....Interesting."
Though it'd give valuable messages about friendship and heartwarming scenes, you'd think it would be more oriented to people without friends or at least socially uncomfortable people because it'd try to fill the loneliness of it's reader with entertainment and hope by showing a lonely guy getting friends through effort and courage. Well it is nothing of the sort.

This manga is nothing palliative.

THIS MANGA DOESN'T TRICK YOU IT LOVES YOU
Though I'm a fan, what I hate about a lot slice of life animanga is that they're purely palliative. It doesn't actually encourage you to be or do any better, it just shows you characters  having the time or their lives instead of you. You watch the former loner mc living his best life so you don't have to, it's contradictory because these type of animanga should or were meant to make you try to enjoy life and it ends up being an self insert show where you fantasize about having that dreamy life that the mc has. Since it doesn't cure you to the core, it only heals you, you feel like there's no need to be cured so you're satisfied with the healing but the healing was originally supposed to cure you?... I don't know if I'm being very clear but I hope you get it.
Now I'm not totally blaming the animanga industry, even though some of em animanga undeniably use it's viewers loneliness to put them in the slice of life hole, sometimes it's just the viewers who ignore the message and go for a self-satisfaction reading session.

Now what I want to go with this is that if you think this manga is about a random lonely mc gradually making more and more friends to make you realize : if he can you can. You'd be DEAD wrong

THE MESSAGE & STRONG POINTS

This absolutely goated chad doesn't have friends because he doesn't want them.

Now you might think that it's a self-defense thing, where he acts tough as the only saving for his ego for being an outcasted, kinda like Hikigiya Hachiman from Oregairu, well you'd be dead wrong too. He literally doesn't need them.

Might have scared you away before with that serious stuff but do not worry, this manga isn't complex AT ALL. In fact, it is excessively stupid and silly. The humor is omnipresent and the story is self deprecating. Now does that means that the manga is for braindeads and that it's never serious ? No, it's somewhat deep and give valuable messages about society and relationships. Now, I'm not gonna lie, if you've watched or read many slice of life animanga and has been around anime for a while it's nothing groundbreaking. I think where this manga stand out from others is at it's core message

Yugami-sama doesn't want and doesn't need friends. Don't take it falsely, the point of the story isn't to minimize relationships importance or to convince you not to make friends. Chadgami doesn't reject social interactions, he rejects the idea of a friend. Gonna keep it short but what is a friend? You've probably had very superficial relationships, and many of us just make friendship for convenience. Not to be alone in a new class, for social acceptance, inclusion, self satisfaction, even for money and a shoulder to cry onto. I'm not trying to make you think friendships are bad because it goes against all my convictions and it's literally necessary for a human to have relationships but the word friend implies a lot of things.
True homies do anything for their homies but it can lead you to consistently do things you don't want to for people who don't deserve it. You never know what's in another person's heart, you can begin to feel a strong connection toward someone but this person doesn't think of you as important. In some cases they just befriend you for benefits just like you start relationships for selfish reasons. Always trying to fit in and being obsessed with trying to have friends can lead you to basically become a mob , hiding your real personality to be easily-liked and accepting everything because you don't want to upset anyone.

Yugami kun doesn't need any of that. It may seems like a cowardly "too much of a handful to bother" mindset but I don't see it as that. He actually takes courage not to depend on others. He's not a lazy defeatist person, he's an hardworker. All this time spend on himself allowed him to know and love himself. He does sports, studies, enlarge his knowledge, make experiences. His no-friends mindset isn't an excuse not to try anything, it's an opportunity to become a better individual everyday. He's always true to himself. He's my model honestly. His nameless relationships may be more valuable than the fake friendships people have. His character is so interesting, you never know why he does the things he does, how he became like that and if he's just a self centered asshole or an altruist guy. I have no idea how the author made any character somewhat interesting with that chad as the mc. You'd think he drives the f*ck outta the plot but again you'd be wrong. Every character and plotline is important and he doesn't influence everything and many would actually argue that the main character isn't even him lmao.

CONCLUSION
I've talked a lot about the substance but the form is neat too. The drawings only get better every chapter and they're actually hilarious. The plot twists, pacing, characters developments and such are decent to good and solid. This is definitely worth reading! I'm not promising you a flawless masterpiece with a complex story but I'm promising you a fun and entertaining story with a somewhat original message. It's simplicity is it's charm.

Many slice of life animanga entertained me but few made me want to be a better person and god 3 full days passed since I've finished this and I still have that 3am turning my life around rush
