KizuGlass

"No matter how rotten the world is. No matter how tired she is with people who don't understand. I don't want her to feel despair."

- Glass to Raphtalia, about Kizuna, Chapter 77 KizuGlass is the femslash ship between Kizuna Kazayama and Glass from the The Rising of the Shield Hero fandom.

Canon
Glass was formerly introduced as a rival to Naofumi, but Kizuna only appeared later when Naofumi fell through the portal. When Naofumi is talking about how he got there, he mentions Glass and L'Arc. The girl nearly drops her spoon and tentatively asks if he met Glass. Fiercely, she shouts that Glass was someone important to her, and was the one that gifted her the hakama that she wore.

When Kizuna arrives back at the home that she shared with the other weapon holders and heroes, she notices how it was still clean even after her long absence. She wonders if it might be Glass's doing because the spirit-woman was particular about things like that. Naofumi asks about her and Glass's first meeting, and she happily begins telling him about their story.

The next day, Kizuna brings Ethnobalt to Naofumi, introducing him as someone skilled at finding people. She asks him hesitantly if she could also find out about Glass, where she is, and what she is doing. Ethnobalt agrees, sharing his desire to notify her that Kizuna was back. According to him, Glass was extremely worried for Kizuna when she was gone. This reminds him of the "child" that Glass was having him carry. Kizuna brightly thanks him for holding on to it. Since the brunette had gone missing, Glass depended on that child to search for her, but it yielded no clues. Kizuna explains to Naofumi that this "child" was a shikigami that she and Glass created; a penguin named Chris. A shikigami is, as Ethnobalt clarifies, "an existence conceived between two people", otherwise known as a child. Chris the penguin was created with a medium that included both Glass and Kizuna, creating a connection between the two. Just as Kizuna is about to be attacked by three Byokko tigers, someone kills them all for her, she turns around to see Glass protecting her. Glass's cold exterior breaks and she suddenly tears up, crying that she finally found Kizuna. Later, Glass descends upon Naofumi, but her dramatic appearance is slightly ruined by Kizuna, who jumps up behind her shouting, "I found her!"

After Kizuna experiences her first wave, she scolds the three vassal wielders for trying to kill an enemy that doesn't even know about the legends. Glass denies this, saying that they challenge the heroes to a fair fight beforehand. Kizuna angrily grabs onto the front of Glass's hakama, scolding her for trying to kill the other heroes. She shouts that if Glass wanted to protect her so badly, why didn't she go after the person trying to kill her? With tears and a blush on her face, the black-haired spirit woman shouts back passionately, declaring that Kizuna was the same; a hero that couldn't fight against people. Naofumi laughs at this, saying that the emotional expression on Glass's face was worth seeing; it was much more understandable than being told to die for another world. She covers her blushing face with her sleeve, then declares that if her fighting was for Kizuna, she would-- At this point, she is cut off by Kizuna, who is shouting into her face irritatedly, reminding her that she didn't like this type of thinking. The shorter grabs Glass's cheeks, and stretch them out to stop her from speaking. Shouting aggressively, Kizuna compares Glass's goals to herself being trapped in the Labyrinth for the rest of her life. Kizuna refutes the claim that they needed to kill the other world heroes, grabbing onto Glass's hakama while still yelling that if she was so worried about her safety, why didn't she go and fight the person who tried to kill Kizuna? With a pleading look in her eyes, asks why the vassal wielders had to go after Naofumi's world, and buries her head in Glass's arms.

Ethnobalt helps them come up with ways that don't require killing the other world heroes. When Naofumi proposes that they go after Kyo in the meantime, Glass agrees and watches Kizuna with a blush.

When Glass loses to Raphtalia during a mock battle, Raphtalia asks her if her heart wasn't in the fight because of Kizuna. Glass dismisses the notion, calling her mistake careless. She talks about what she likes about Kizuna, focusing on her future, and how the brunette is always hopeful. Glass states that she never wants Kizuna to suffer, no matter how rotten the world is. Breaking off, she begins to say she loves something/someone, but doesn't finish the sentence.

Naofumi sets up a trap for Kyo's assassin. It works, and a female assassin breaks through Kizuna's door soon after. Glass gets extremely angry at her for ruining Kizuna's home, and also defends Kizuna when the assassin completely ignores her offer.

Fanon
Kizuna and Glass are polar opposites in almost every way, yet they get along extremely well. They seem to have been friends for a very long time, as shown when Kizuna was explaining her relationship with Glass to Naofumi. Glass also tends to blush a lot around the topic of Kizuna. They have both claimed that the other person is someone extremely special to them. In the Infinite Labyrinth, Kizuna claims that the hakama she was wearing was one given by Glass. It's important to note that hakamas are delicate, but the one that Kizuna was wearing had no holes in it, therefore, she must have been treating it with care. Likewise, when Kizuna finally arrived back home, she noted how clean and neat the house still was, wondering if it was Glass who dusted and kept the house in neat condition.

Glass was heavily implied to be gay for Kizuna in the web novel. This wasn't canon though, the author let his fans decide epilogues for certain characters, like Glass. But the outcomes became extremely controversial so he never ended up confirming the canonicity of those statements.
