From Chibi Manga:

Collection of oneshots. Most of these stories were reprinted in Filament.

From Yuzu Scanlations:

“I’ve already loosened my ass up…”
College student Ise Natsume may look like an ikemen, but he’s just a silent person with a lifeless face. Even though he has only a few friends, let alone lovers, he falls in love with someone he just met. That person is Amano Haru, a classmate who’s cute, friendly, and expressive, the exact opposite of Natsume.
As he watches Haru from a distance like a stalker, his friend decides gives him a warning: “That guy has no morals. He’s a pleasure seeker who will do anything. In other words, he’s a bitch!”
“There’s no way someone as cute as him would do that…” is what Natsume believed at first until Haru intrudes into his home and tells him, “They found out that I was three-timing them, so let me stay over~!” After Natsume reflexively pins him down and they have sex, they end up becoming sex friends. Natsume doesn’t want just the pleasure, he wants to date Haru, but Haru doesn’t agree……
A pure love story about how a slow to mature ikemen and a cute playboy go from being sex friends to lovers.

If you've ever had a guy steal your girl through the use of a squid-related judo move, this oneshot will definitely speak to you!

It straddles the line between being comedic and just plain odd. If I had to give it some deep meaning, I'd say it speaks to the futility of life. Sometimes the bad guys just win, and the good guys get embarrassed.

It's closing ceremony and romance blossoms amongst the bubbles...

1-2) Dive

Short story about a boy, his mixed half brother and a dog.

4) Kotteru Otoko

5) Gakuen Tengoku

Kaitai is a science-fiction-ish BL story of bio-engineered humans, sinister policemen and moody scientists with mysterious pasts.

Set in a depressing, fictitious London from somewhere in the near future, this manga is representative of Ishihara's earlier, non-yaoi works; rough, sketchy artwork accompanied by an interesting plot the likes of which is rarely seen in the shounen-ai demographic.
