Slash Kakashi/Iruka

An excellent story that covers Iruka from when he first meets Kakashi at the age of 6 until they are involved in his late 20’s. The story ends soon after Naruto has gone on his training trip. This is a character driven story and it is beautifully done. The story is from Iruka’s point of view and keeps a lot to canon. Here he meets Kakashi many times before the exams both as an Anbu and as the Copy Nin. Iruka falls in love with his Anbu that saves his life several times and eventually becomes his lover even if he never sees his face. When Anbu-san must say goodbye Iruka is heartbroken but understands. He slowly becomes friends with Kakashi after meeting on a mission. Eventually he falls for him and near the end of the story he finally puts it all together to realize that his first love and his last love are the same. You get a depth of feeling that is surprising when you realize just how slow the romance in both cases is going. While there is action and some sex that is not the driving point of the story, instead it is just how much one person can become woven into the life of another. A satisfying, feel good read that is welcome any day.

I've Got You (Kakashi/Iruka)

Iruka is so overlooked mainly because he is a Chuunin Instructor. What people forget is that he is the best instructor in the academy and regularly turns children in fighters. In this story he is in the wrong place at the right time to see an attack on his village. The thought of his children and friends in danger pushes him to extremes. Luckily his love of history shows him how to stall any further attacks until help can arrive. When Kakashi sees his secret love in danger he proves to Konoha just why he is considered so dangerous. Nothing will stand between him and his love. You see the dangerous warrior and killing machine Anbu that he hides behind his lazy persona. He decides the only one that can help Iruka heal is him and he calls in some friends to find out who hurt his beloved and tried to destroy his village. By the time The Hound, The Fox, The Feline and The Turtle get done Kami have mercy on them for they have none.
An excellent story with a little seen side of Kakashi and Iruka. I hope the author gets around to a sequel soon.

All the Broken Pieces (Kakashi/Iruka)

This takes place in the time skip and it is all due to a bet. Tsunade bets Asuma that Kakashi can turn Iruka into a Jounin in two months. No one least of all those two expected a romance. This is not a jump into bed and fuck like bunnies those some of those are good as well. It is broken into 3 parts, the first part is funny, the middle is horrible (torture scenes), and the last part is the mushy scenes. An all around good story.

Tricks and Traps (Kakashi/Iruka)

A romantic justification of why Iruka is not a Jounin. Well sorta, Ibiki and the Hokage test Iruka and the first test is to capture and deliver Kakashi. It goes downhill from there prepare to laugh like hell and the lemons are hot.

Tears, Blood and Fluff Bunnies (Kakashi/Iruka)

Exactly what it says a series of one shots that capture moments in Kakashi and Iruka's life. I liked it, some make you laugh, some make you sad, and some make you go awwww. Something for everyone a very enjoyable fic.

The First Step (Iruka/Kakashi)

It's funny, sad, and fluffy at the same time with some great scenes. I love how Kakashi's perception of Iruka changes but Iruka is not some super ninja hiding behind a mild facade. The scene where Gai interrupts is hilarious.
