One year has passed since the beginning of the war between Russia and Japan - and Russia is winning. However, Japan still has hope; the Raimu unit is still in action with five new members, and a new man at the helm: commanding officer Kyoushirou Inukai! With bravery and a heroic nature, Kyoushirou will lead Aya, Shuro, Tsumugi, Ii and Kasuri to victory against Princess Fahren and the rest of Japan's enemies! That is, unless the girls manage to get in his pants first!
Earth has been struck by a major catastrophe, causing most of the land to be covered by water. Meet Aika Sumeragi, a scavenger who unearths everything from nostalgic treasures to lost technology from the depths - for a price. During a routine assignment to find the rumored energy source Lagu, she finds herself face to face with a man called Hargan and his harem of scantily clad women named Delma! Now, with danger afoot, Aika finds herself smack dab in the middle of a conspiracy involving secret weapons, a crazed scientist and of course, panty shots galore!
Both have panty shots galore on ships fighting against their enemies. Both have a high ecchi count in a erotic way with female to male interactions. Mindless plot that doesn't take much to understand for both but if all you are looking for is good old fanservice check both of these out.
