Dimensions: It All Begins with a Summons from the Dragon God

For no apparent reason, Dragon God Salama summoned someone to the Dragon Ball world. Seeing how weak and helpless the one who summoned him was, he could only grant them Saiyan blood. What? You're telling me you summoned me on a whim? Luckily, as someone who had transmigrated, the influence of the dimensions granted me the ability to travel through the myriad worlds. Dragon Ball, Naruto, The King of Fighters, everything... How should I put it? I'm not that strong. I just happen to enjoy grinding out passive abilities.
