It is the 38th year of the Meiji Era. The Russo-Japanese War that started the previous year had intensified. The Japanese Army was worried about the overwhelming strength of the Russian Army and the mysterious Raimu Army behind the scenes. But, there was a light in Japan. The Lime Tai Army!
Kyoshiro Inukai has just been promoted to Commander of the new Lime Unit Army, created in the wake of the dissolution of the previous Lime Unit. It consists of his childhood friend Tsumugi Shima, half-Russian Shuro Naoe, studious Nishiki Ii, clumsy ninja Kasuri Hattori and aspiring nurse Aya Nabeshima. In the meantime, Kuki has added a new familiar in the form of a flying squirrel named Toushi to her ranks.In Russia, a new group of fighters called the Faden Knights, carrying on the legacy of Rasputin, have started attacking. It's time for the Amanohara to set sail once more. The problem is that Kyoshiro knows everything there is about being a soldier, but he's unprepared to be a teacher.Like Senkitan, Lime-iro Ryukitan X (Cross) ~Koi, Oshiete Kudasai~ started off as a Visual Novel battle sim game before receiving an anime adaptation of its own in the winter of 2005.
Lime-iro Ryukitan X provides examples of the following tropes:
Chaste Hero: Unlike Shintaro, Kyoshiro never catches onto the fact that the girls love him, even though he's closer to their age. It takes a confession in the middle of the final battle for him to even realize it.
Class Representative: Nishiki. She always carries around her rulebook to make sure her classmates stay in line.
Clingy Jealous Girl: Tsumugi really doesn't like it when everyone else tries to make a move on Kyoshiro. She believes she got there first.
Cool Horse: Nishiki's Raimu is a samurai on horseback — complete with horse.
Deliberate Injury Gambit: Kyoshiro willingly rams his head into the wall to injure himself so Aya can become confident in her nursing skills. The lengths he'll go to...
Faux Action Girl: After Kyoshiro gains his own Raimu form, even though it can coexist alongside the girls' summons, they always give their powers to him instead of fighting on their own. This fixes itself by the end of the series, though,
Furo Scene: In lieu of her bedroom, in the anime, Kuki has a hot springs set up in the ship. Still an oppurtunity for fanservice, just of a different kind.
Golem: One of these awakens in the temple, being a transformed state of the Egg.
Powered Armor: The five girls' hearts combined grants Kyoshiro a suit of flying armor, turning him into a Raimu. The girls turn into their Raimu in the final battle, and play a more direct hand in the fight.
The Power of Love: As in Senkitan, but this time, it's both more grandiose and more direct.
Puppet King: Lady Faden is Linen. An actual puppet was in place in scenes where the two of them were in the same scene.
Rated M for Manly: Kyoshiro is overblown in his idea of manliness, to the level where he becomes a Chaste Hero. His manliness and being a soldier take precedence over the harem he's building up.
Save the Villain: After seeing how Cashmere is treated by her boss, Kyoshiro makes the effort to save her, even after she'd been trying to kill him for so long.
