It is a university of animals, located in the green nation "Zoo" of remarkably rich nature. It is the highest education institute, housing many geniuses of top-level IQ in its campus of forests and plains. It is told that there is one specialized course in this institute for everything that can be described as "knowledge", and students choose their courses based on their respective talents and interests. Students and academic staffs treat each other as comrades in "Great Nature" without barriers. They study, discuss and keep on learning. Even if they seem scratching indolently or slumbering with yawns, their brains always persist in challenging the puzzles and mysteries of the world...perhaps.
The clan's theme of "knowledge" is present in their skills as well, as many units gain a quick surge of power (usually in intervals of 4000) in exchange for being retired at the end of the turn, which can be interpreted as "studying for a test" and "resting after the test". They combine this with effects activate when the rear-guard is retired during the end phase to generate advantage. The clan also has a focus on drawing cards, which can also be interpreted as "gaining knowledge". By stacking multiple of these effects into a single rear-guard, the end result is usually a high power rear-guard that then generates large amounts of advantage. The clan's keyword, "Success", puts an emphasis on reaching a certain amount of power for their effects, and the achieved state can be seen as a reward for their constant focus on knowledge.
The Honorary Professors and their students focus more on powering up their rear-guards and giving draws as a condition when declaring an attack while doing multiple attacks to continuously stack these effects, allowing the player to draw massive amounts of cards at the end of the turn.
Leo-pald and his different forms specialize in recovering the rear-guards that were retired at the end of the turn by either calling them back or searching another copy of them.
Hammsuke and his classmates focus more on having their abilities search copies of themselves to filter the deck and manage resources rather than spamming their draws.
