"Yes, from today, you’re all Kiznaivers."

This is a group by select invitation. Only those who are deemed fit, who have a particular trait worthy of the title shall enter. Everyone here has something unique about them that makes them a Kiznaiver. They don't show it on the outside, but in a way, we are all similar in the aspect of everyone possessing something unique, and a bond strengthened by shared pain brings us closer together, which would be truer to the anime but doesn't apply as much in real life.

The word "kizuna" in Japanese translates to bonds (between people), (emotional) ties, relationship, connection, link [Noun]
The premise of the story is these are the names of sins that have taken new, more modern-day or contemporary names in present-day society.

Characters from the show that embody us:
Me (Eke) - Chidori (Goody-Two-Shoes)
Leo (Altalio) - nickname "Kacchon" (Gudon/The Imbecile in referring to a person who is apathetic)
Ethan - Yoshiharu Hisomu (The Immoral)
DesignerMoodSwings [aka MixtapeFiretruck]- Nico Niiyama (The Eccentric Headcase)
Shirou<3 [aka SayaF*g] - Tsuguhito Yuta (The Cunning Normal)
Tiwill - Hajime Tenga (The Musclehead)

"Everyone wants to connect with someone else." – Noriko Sonozaki

Note: F*g being a 4-chan slang for when you're a fan of someone/something.

A comment on Berserk. We cannot continue grieving forever on the passing away of its author. We must learn to put it behind us, but always remember the profound influence it had on series that took inspiration from it, and the readers who partook in it.
And for a more personal take on it:
I will never forget the impact Berserk's first season had on me in the year of 2016, when I first started watching anime, and I would later quit for good in 2018 until 2021.
