Pen Contract (ペン契約; pen-keiyaku) is a family introduced in PB39, the anniversary Premium Box of Pentan, possessed exclusively by the Contract card, The Partner Pentan, and the Contract Advent cards that support Partner Pentan.
As the name implies, it is the "Pentan (ペンタン)" version of Contract Spirit dedicated family for a deck that revolves around Pentans, one of the most popular mascots of the game, and one with the longest history.
Cards in the family include The Partner Pentan, and various Contract Advent forms featuring different Pentans like The President Pentan and The God Pentan. Interestingly, being a Brave, the revival version of The SongBirdGun Pentan Blaster also owns the family, so as to support the Contract Advent Pentan cards via Contract Reload.
