Mary, a suicide prevention AI

From Yaoi Is Life:
Passionate bird shop owner Masaka Toru meets foreign exchange student Fon-kun, who now makes regular visits to the shop. What is Masaka to do when he receives an unexpected confession from his regular? And what is Fon-kun to do with a parakeet as his love rival?

Having lost his confidence as a bread-maker, Masaki works making bread in a bakery and boarding house run by a pair of sisters in Otaru, Hokkaido. Seeing the smiles on the people eating the bread, he grows to maturity one step at a time as a maker of breads.

Makabe Masamune has changed himself greatly for a single reason: he wants revenge. Contrary to his past, he has worked hard to become good-looking in order to carry out this goal. Faster than anticipated, he even meets the target of his revenge the first day after transferring in.. Adagaki Aki! He wastes no time beginning his plan, but revenge doesn't come easily.

The new manga will tell "after stories" about the characters, including Masamune, Aki, and Yoshino, among others.

It's been one year after Makabe Masamune and Adagaki Aki got together, and they're temporarily on a long-distance relationship when Aki moved to Sapporo to attend university. Koiwai Yoshino, who continued living at Aki's house, finally got accepted into Juntama University after failing their entrance exam last year, and she reunited with Makabe, now a second year student here. However, trouble immediately started when they got dragged into a game by the new freshman Iroha, and she claimed Makabe, who inadvertently "won" the game, as her "lover" against his will...

Even though Makabe Masamune's lost a lot of weight, change his family name, and stood on the top of the caste as a super hunk, somehow happenings with “ReOOO” occur every morning he comes to school, confusing Aki and his other friends...

Chika and Masaomi are childhood friends, both raised by single parents, and Chika would often spend time at Masaomi's house. When Chika's mother died in an accident, Chika would have to move away to live with distant relatives, leaving Masaomi and everything behind. Instead Masaomi proposed, "You should marry me. Husband and wife. For real."

"So that means..."

"Kissing, making love, everything. Can you?"

Chika's answer is...

Shirahane Masato, a man who appears in unexpected places at unexpected moments... Just who is he really!?

From CPM:
The Devil's Castle was a dark and somber place, until the good-hearted apprentice ASARELLA stumbled on it in a goodwill mission, against her master's wishes--the archmage ELIWHO. Things sour quickly, as Asarella was bound with a blood pact to the Devil, KAINEN. Little did she know, the mage harbors a secret love for her that will only complicate her training for the upcoming apocalyptic battle. This sets up the most unusual love triangle of all space and time.

From Evil Flowers:
The story shows how Caien became a demon lord, is about his relationship with Rakin, The King of Speira, and the love triangle between the 2 with the beautiful Rea of the mascan race. Asarella also apears, but the story seems to be concentrating more on Rakin and Rea.

Note: Read this after you read 'Masca' as this series jumps right into it with no introduction and you will be confused if you read 'Masca:The Beginning' first

Did you think Masca: The Tale of the Great Mage of Hessed was over? Masca: the Kings is the sequel of Masca, in which Asarella goes on a journey to save Kainen. However, the first two volumes focus quite a bit on the development between Rea and Rakin (Kainen's beautiful ex(?) and another demon king).

Contains 3 oneshots:

1. Mascara Blues

After seeing another guy lose his "sparkle", Mugino goes to talk to Shuuya but finds that he has a "sparkle" too!

2. Draft of Romance

She soon meets a hairstylist, Mashima Eiji, who asks her to be his hair model. When she tells her friends this, they warn her not to fall in love with him because hairstylists are known to "play" with their clients. But she can't stop thinking about him!
