Lagoon Engine (ラグーンエンジン ^?) is a manga by Yukiru Sugisaki. It's been suggested that this is a prequel to Lagoon Engine Einsatz,^[1] but no statements have been made to support this idea.

The main protagonists are Yen and Jin Ragun. When put in a certain order (Ragun Yen Jin) it sounds like "Lagoon Engine".

Volume 6 was released on December 1st, 2009. Volume 7 was released in Japan only on the same day.

Trivia --- Yen and Jin once appeared in D.N. Angel in cameos in the manga and anime. In Volume 9 there is a page where Yen and Jin are carrying their Gakuki and the anime, they appeared in Episode 10 wearing suits.

Plot

Lagoon Engine revolves around two characters: 12 year old Yen, and 11 year old Jin. While Yen's intelligent, calm, and thinks tactically, Jin's hotheaded and rushes into battle.

The Ragun family is dedicated to defeating ghosts, evil spirits, etc. - known as 'Maga' Yen and Jin just happen to the successors of the family, and they have to fight Maga too. In short: Yen and Jin are Gakushi.

Both Yen and Jin have Maga - though not evil maga. Yen's Maga is called Koga, while Jin's maga is named Sora. Koga is good with gathering information, analyzing and remembering things, though he's extremely bad at attacking. Sora has no intellectual power whatsoever, but his attack power is very high.

How battles work When Gakushi fight maga, they must create a barrier. Within the barrier, the two opposing beings cannot see each other, and they don't know each other's names. When they guess the opponent's name correctly, they can clearly 'see' the maga. Their attack power will be at 100 percent, and the other side's attacks are ineffective. This is what yuusei is.

As a result, each side must keep their names from the other as much as possible.

Gakushi have their own names too - not names that their parents gave to them, but their own names. They never give any clues about their names. This is called an Omi name. No one but themselves know their omi name.

Yen and Jin get tasks from their father to complete which usually involve fighting maga.

Kamen Kugutsushi The enemy. Gakushi cause maga to calm down to become allies instead of causing chaos and destruction. The Kamen Kugutsushi are the total opposite. They rile the maga up, causing them to become angry and cause uproar. They've stolen nineteen of the books that maga have been sealed in. So far in the series, one has been destroyed, so there are eighteen left. Will Yen and Jin find them?

Characters

Yen Ragun (等軍焔 ^?)

He's intelligent, and good with making inferences, as is his maga. He's a good gakushi and often teams up with his brother while fighting maga. As a perception type, he can understand Maga. As shown in the second book, he hates slimy things, so he hates natto (fermented soybeans).

Jin Ragun (等軍陣 ^?)

Yen's younger brother. Almost the complete opposite. He's hotheaded and rash - seemingly not very bright either. However, he's still loyal to his brother, and loves him very much. He's never quiet and hates peppers.

Ayato Housui (峰水綾人 ^?)

Ayato is related to Yen and Jin. Apparently, he's their cousin. He knows of Yen and Jin being Gakushi, and isn't bothered by it at all. He's quiet and polite. One of his more frequent nicknames is "Aya".

Miki Kirishima

Miki is a girl in Yen's class who has not attended school for two years because of a deadly disease that confines her to a hospital. Her dead dog, Tom, was lead back to her by Yen and Jin, and is slowly becoming a maga. Yen thinks she'll become a Gakushi.

Erei Moribayashi

A friend of the Ragun brothers. She's loud, and rather hotheaded. She doesn't seem to know of the Ragun brothers being Gakushi. She seems to have taken a liking to Ayato.

Shintaro Nagasaku

He's twenty-eight, single, and works as an editor for Yen and Jin's mother. He seems to live at the household, and is rather strange. In fact, he likes to wear skirts.

Akane Ragun (Mari)

Akane is a very popular author. Her works never meet the deadline, but the books still end up being ridiculously popular. Although her true name is 'Akane Ragun', it seems that her penname is 'Akane Mari'. She's the mother of Yen and Jin.

Hideaki Ragun

Hideaki is the husband of Akane Mari and the father of the Ragun brothers. He's a very experienced Gakushi, and extremely powerful.

Suguru Mikami

Suguru is a gakushi of the Mikami. The Mikami is a 'branch' of the Ragun. He appears to be the silent type at first - strong, cool and collective - but that's not all that there is to him. He hates being called "Branch Family" and Jin for calling him that. Besides that, it's very possible for Suguru to be nerve-wracked.

Koga (Maga)

Yen's maga companion. Koga cares for Yen very much, and reflects on Yen: Koga is intelligent, and makes a good team with Sora - Jin's maga. However, Koga lacks in attacking.

Sora (Maga)

Jin's maga, and also seems to have as much energy as Jin. Sora has no intellectual power whatsoever, but his attack power is very high.

Shinno Zai

Shinno is assumed to be a Kamen Kugutsushi, which is the enemy of the Gakushi. He attends the same school as Ayato, but Ayato has no idea that Shinno's Yen and Jin's enemy. Not much is known about Shinno.

Hodou

Hodou is Shinno's servant. He calls him master and does his bidding. He attends the same school as Ayato as well. Not much is known about Hodou, either.
