Thank god for Date reminding him that despite all the losses, he still has Haruka. The fact that even Kiryu realizes this and went in a near total breakdown is enough to make tears flow. From father figure, old friends, and the woman he loves. The fact that once everything is said and done, you just realize that Kiryu has lost nearly just about everyone in his old life.It's little wonder how this finally breaks Kiryu down after the many other deaths he had the misfortune of witnessing. The only comfort as she dies was both Kiryu finally revealing his feelings for her and Haruka at her side. Finally, she reunites with both Kiryu and Haruka, with the sense that finally things can calm down.only for her to witness Kiryu and Nishiki beating the crap out of each other and dying from a gunshot wound from Jingu (again, the father of her child). Then she made personal sacrifices that involves lying to her own child for the sake of protecting the kid. When she does regain her memories years later, Kiryu is in jail, Nishiki has fallen to a much darker path, and she and her own daughter are being marked for death by said daughter's own father. Then she loses her memories of him after Nishiki's killing of Dojima (not to mention the events that led to it) which traumatizes her severely. It is clear that Kiryu loves her and she does in fact have similar feelings for him. and Haruka went into severe grief over her. If that's not bad enough, Yumi, Kiryu's old friend thought to be missing dies from a gunshot wound, meaning both of your best and oldest friends died in the same night. Then after you fight and beat him, he later gets back up, comes to his senses, and sacrifices his life as a way of redemption, after a decade of ambition and burning bridges. Imagine this, your former best friend/brotherly figure is now one of your main adversaries, you're both clashing way more than you ever should, and that is already tragic. Nishiki's sacrifice at the end of the game.Not to mention Kiryu and Nishiki sitting far away from each other to remind us that their relationships were already strained to begin with.Kiryu: 'Why.? After everything Kazama-San DID FOR US!?'

From there, you can really tell that Kiryu felt extremely betrayed and enraged by his blood brother and that their relationship was slowly deteriorating to the point of no return. However, the biggest gut-punch (No pun intended) comes from Kiryu's devastating punch to Nishiki in Serena after realizing that he was the one who shot Kazama, a father figure to Nishiki and Kiryu.This became even more tragic after Yakuza 0 shows how loyal Nishiki was and how far he was willing to go for Kiryu, and for those who hadn't experienced the first game but played Kiwami after Yakuza 0, watching how two loyal lifelong companions became bitter enemies and fought each other with everything they had was heartbreaking.

It was tragic enough that Kiryu and Nishiki, who grew up together, were like brothers to each other and would do anything for the other, ended up losing all of that after ten years, which culminated in a brutal final showdown between them in the first game.

Worst of all, Kazama likely passed before Kiryu finished telling him this.

One memorable example is the death of Shintaro Kazama, who despite revealing his darkest secret to Kiryu, is forgiven and considered to be the only parent figure from the latter.

Moreover, the little ounce of friendship that Kiryu had with Nishiki was soon dissipated as we can hear his rage-filled scream.

You can see how much they meant to Kiryu as they were an important part of his life that made him who he is.

The fact that Kiryu was too late to save both of them from Kazuto Arase was just an extra punch in the gut. ' But even if we wanted to, we can't go back ten years.'
