OVA is a simple system designed for the sorts of storytelling found across genres in anime. Its pregens exemplify this, ranging from a pair of rivals from a clan of assassins to a combat robot trying to become human, to a space police woman and her android partner. Each contributes its own setting features, be they a morally dubious corporation, corrupt government agents, or magical monsters-of-the-week.
Characters choose a set of Abilities and rate them from +1 to +5; these both provide direct bonuses to relevant actions in the form of extra dice and define special abilities like Teleportation or being a Spirit Medium. They can also provide secondary benefits; for example, a character with Tough +3 not only gains that bonus when doing something that requires resilience and durability, but also an extra 30 Health points. But characters also have Weaknesses, rated from -1 to -3, that work much the same but in reverse. Characters also have a pool of Health and Endurance, the latter of which being a faster-recovering resource that’s spent to power certain abilities or buy bonus Drama Dice.
Whenever a roll is called for, if no bonuses or penalties apply, you roll 2d6 and take the highest as your result; if you roll doubles, add them together to get the result instead, so that you can get results higher than 6 if you roll two 4s, 5s, or 6s. If there are bonuses or penalties, however, you add or subtract an appropriate number of dice, and treat any multiples the same way; a 6 and three 5s, for instance, is a result of 15. If your penalties would reduce the number of dice you roll to zero, instead roll two dice and take the lower, with additional penalties adding more dice to that roll (obviously, you don’t add duplicates together on a negative roll). After generating your result, you compare it to the difficulty to see if you succeeded or how well you did, in the case of tests without set difficulties.
With battles (mecha, magical, and otherwise) being a staple of many anime genres, there is also a robust attack-building system, allowing you to add Endurance costs or downsides (charge up times, accuracy or damage penalties, etc) to your attacks to get a variety of benefits in exchange (ignoring armor, drainging life, etc). Combat itself is otherwise fairly simple, with each attack having an associated Damage Multiplier and any successful attack dealing damage equal to the amount by which it beats the defense roll times the multiplier.
Attempting to sway the affections of the landlady at the building you all live at is difficult in the best of times. The periodic ninja attacks, corporate espionage and magical conspiracies that you and your fellow tenants bring on don’t really help. But this alien invasion business is really out of control!
