Start from the Milky Way with Shining Tiga Doll

With the Shining Tiga Spark Doll I just bought, I traveled to Ultraman Galaxy.
Pick up the Zaki doll and get the Leonix Battle Instrument.
Possessing both light and darkness and the power to summon monsters.
Starting from the Milky Way, traveling through parallel universes, witnessing the light of human beings themselves.
(Easy and semi-invincible, no heroine, logical, plot development, slow pace, not a cool novel, you can use some brain to read it)
(There is already a world, Milky Way - Tiga - Mebius, the rhythm is very slow, it is not a cool novel, it is not a cool novel, comrades who want to read a refreshing novel, turn left when going out)
