So, you're newly out of the closet. Likely in your late teens or early twenties, the world can be a confusing place for a young queer person (especially in pre-New Millennium works). How do you find a date? How do you transition? Where can you meet people similar to you?
Here is where this trope comes in.
The protagonist will meet an older character. Out, proud, and confident, they will help the lead with their troubles and be a shoulder to cry on if things go sour along the story. They also inspire the protagonist and show that not all queer people end up miserable and/or dead.
A large number of Coming Out Stories have this type of character. They're almost never a Love Interest (and oftentimes they are in a relationship already). Instead, they're more of an older sibling figure and a confidant to the main character. If they're in a relationship then they and their partner might act as a Beta Couple to the lead.
Compare to Cool Big Sis and Big Brother Mentor for more general examples. Lover and Beloved is a usually gay male trope where the lover is also the character's mentor.
- In Bloom Into You, Sayaka, who realized her liking girls was not just a phase after meeting with Touko, seeks advice from Miyako, a lesbian café owner who's in a relationship with Sayaka's own teacher Ms. Hakozaki.

- In given Uenoyama has a heart-to-heart with his college-aged bandmate Akihiko, during which it comes out that he's crushing on their newest bandmate, Mafuyu. Uenoyama gets uncharacteristically vulnerable, asking Akihiko if he thinks there's something wrong with him. Akihiko calmly reassures him that he's fine, going as far to reveal that he's been with men himself, turning it around and pointing out that Uenoyama won't say there's something wrong with him.
- Love Me For Who I Am has Satori Iwaoka, the owner of Café Question. Satori's only sibling is Tetsu, but she often acts like a Cool Big Sis to the whole staff of the café, and as a Transgender woman she's often able to empathize with their issues and offer advice and support. In particular, when Mogumo's presence in the first volume leads to a rift between the staff over their standard "I'm a guy dressed as a girl" introduction, she encourages all of them to share their point of view on the issue to come to a compromise. This eventually resolves in Mogumo being able to stay in the café without compromising their identity and helps Mei realize she was a closeted trans girl.

- Meanwhile, Tasuku wants to become a figure like this to Misora, a younger patron, after remembering how alone he felt when he was younger and frightened by the realization he was gay.
- While it's hinted that Misora would like to have a relationship like this with Tasuku, Tasuku realizes that the person Misora truly looks up to is "Someone," glowing upon receiving praise from her and admitting his admiration of her mystique and aloofness. Unfortunately, the qualities he admires so much mean that Someone isn't actually that good of a mentor figure, and when Misora reaches out to her after the events of Chapter 9, he's left even more hurt when she is unable to offer him any comfort or advice.
- Shonen Note: Boy Soprano, Yuhki Kamatani's pre-Dreams work, has Minoru Aoi, a former soprano who becomes a sort of mentor for the choir as a whole. Minoru is initially introduced as Yutaka's big brother, but one day Mito runs into them wearing a skirt. Upon being questioned about it, Minoru displays a casual, almost fluid relationship to gender. Mito, likewise, is initially introduced as a girl but is uncomfortable with "feminine" things and longs for a deeper voice, hinting him to possibly be a closeted transgender boy. Mito forms a sort of Intergenerational Friendship with Minoru and later is inspired by them to try dressing in a way more comfortable to him.
