The Reincarnated Trio that the Nobility shunned shall become the strongest

Loud House / Original Anime Crossover
Featuring Duke Loud (1600), Lincoln Loud, and Stonewall Titlow (me) as the reincarnated protagonists.

By some bizarre circumstances, three souls from two distinct times reincarnated along with plenty of members from both times in another world. But as the three siblings Luke (me), Albert (Duke Loud), and Kenji (Lincoln) weren't like the other nobility due to certain stereotypes and in the case of Kenji being blessed with elemental magic, which is considered weak magic, and with Albert being blessed with creation magic, which is also considered weak magic, they are first shunned and then banished by the nobility of the kingdom they grew up in, ripping them away from their beloved siblings and friends that cherished them. Deposited into a barely populated region still teeming with natural resources but overrun by powerful monsters, unbeknownst to his younger siblings, Luke begins to form a plan to reclaim his younger siblings' stolen inheritances. Drawing on the cheat skills he had managed to hide from the other nobles (and his own siblings) plus his incredible optimism, determination, brainpower, and a couple of secrets he has hidden from everyone else, the eldest of the siblings sets out to turn them into the strongest.
