The Item World returns with different aspects of it being renamed to a Sea Theme. The Item Bag and Warehouse have been merged into one, with different categories for each Item and the player can have up to 999 Items. Throwing is not limited to throwing straight similar to a Gun's range, but the player can now throw freely within their range similar to the range of a Bow. Stronger Enemies bills have been changed to a Cheat Shop feature and can be changed freely.
The player can also gain a very small percentage of the enemy's stats when he/she defeats enemies in the Land of Carnage mode. The cap can also be increased further due to the new Rasetsu Mode which increases the HP/SP cap to 400 billion and all other stats can have a cap of 999 million. Other changes are that enemies and players can have HP/SP well beyond 10 billion, up to 99 billion, unlike the older Disgaea games. Another feature is the Cheat Shop, which allows the player to modify certain attributes such as lowering the gain rate of something like experience, to raise the gain rate of something else, like Hell. Likeability also affects the strength of collaboration attacks used when Monster Mounting depending of the relationship established between a humanoid character and a monster character, as well as the strength and probability or Team Attacks. Characters can also build relationships with each other and their compatibility is determined by a heart scale of 0 to 5. A humanoid character is able to ride on top a Monster allowing the humanoid character to attack on top of the monster while the monster takes damage for the humanoid character.
Monster Mounting is a new feature that replaces Magichange from Disgaea 3 and Disgaea 4. Gameplay in Disgaea D2 remains the same as other core Disgaea games in the series. The Krichevskoy Group blames Laharl for the sudden appearance of the flowers, believing it to be an act of aggression from the angels in retaliation for the events that occurred in Disgaea: Hour of Darkness. Compounding the issue is the sudden appearance of rapidly multiplying Yuie flowers that are changing the atmosphere of the Netherworld. A particular group of the late king's former vassals, called the Krichevskoy Group, are trying to usurp him and put someone that they find to be a more suitable leader on the throne. However, the demons of his Netherworld do not respect him or his authority. Laharl has been crowned Overlord of his Netherworld and has taken his father's place on the throne.
