I've Been Reincarnated as a Gacha Summoner?!

Given a second chance due to his unfortunate life, Jett Levine finds himself reincarnated into the mystical world of Fantasia, filled with magic and monsters, but he did not arrive without a gift of his own:
[Gacha System Activated]
An ability fitting for the man who tests fate time and time again, able to use his system to summon anything–be it a weapon, mythical creatures, magic, or even beautiful woman, all of varying rarities and power–so long as he has the proper coins to do so.

In this mysterious world, fantastical beasts among other obstacles stand in his way, along with other "Reincarnators" -- those who possess systems of their own.
