らいむいろ戦奇譚 (Lime-iro Senkitan)
In the midst of the Russo-Japanese war, a Japanese naval ship, the Amanohara, was assigned to attack Russia's major base at Port Arthur (Lushun). Shintaro Umakai, a Japanese diplomat in Russia, was called back and went to Sapporo to teach at a girls academy. Little did he know that the academy is on board the Amanohara, and the small class of five girls Shintaro assigned to teach are the Raimu Unit - girls with the ability to summon powerful beings to fight for them. Not only Shintaro had to teach them, he needed to lead them to battle himself. Meanwhile, the enemy had someone who knew Shintaro very well...
Lime-iro Senkitan is based on a hentai game of the same name. A 2-episodes OVA was released as sequel, and a new TV series is produced this year in Japan.

A show without the hentai elements of the original game, which makes it OK to watch. An interesting series of the "all girls fall in love with the sensei" variety.

2 episodes OVA
Continue the story after the end of the TV series, and as a bridge to the next sequel: Lime-iro Ryuukitan X (らいむいろ流奇譚). Slightly more ecchi than the TV series.

Based on the same hentai game, a new 5-girl team is assigned to a new guy from the navy.
Not going to watch it because the character designs are simply not appealing to my taste.

And now for the big bad naughty stuff...
Warning: Hentai contents!
As far as I know there are two hentai games and one "mahjong" game for PC. Never played them unless I can find a copy...
There is a PS2 version (definitely non-hentai...)
