Pool-type Suppression and Pool-type Suppression + are Rare, and Epic materials dropped from any of the Rummy-type Others in the game. You may have to kill them for a while until this material is found, depending on the rarity of the material that you need.
These are the Pool that you can get these materials from and where they can be farmed:

If playing as Yuito, the Kikuchiba——Mid-Level Shopping District and Upper-Level Construction Site is the best place to farm. Just make your way through both of these areas, and you’ll encounter many Fuel Pools that melt with Pryokinesis. Once done, teleport to a new location, then return and rinse and repeat.
If playing as Kasane, head to Abandoned Line 9—Hirasake Station Entrance/Exit, and on to the Inside Abandoned Line. Wipe the first area, then when you enter the Inside Line, kill the Bile Pools in front of you, then enter the area to the left. You’ll fight some more in here, as well as some Rat-Ruts.
Rummy-type Suppression is used a lot in the exchanging of gifts to increase your bond with characters.
