The protagonist travels through a parallel urban world. This world has Pokémon and has awakened the "sharing ability". It can permanently share a skill and physical energy of a Pokémon with a favorability score of over 60. The shared skills can be strengthened as the Pokémon grows, and the physical energy will be integrated into itself to help improve its realm.
Realm difference
1. Bond Realm: The initial realm. When a human is 10 years old, he or she can activate the first soul bond position through an official ceremony and bind a primary Pokémon.
2. Growth Realm: You need to absorb the energy accumulation brought by Pokémon upgrades, and you can activate the second bond position by breaking through the bottleneck.
3. Mature state: To activate the third bond slot, the first two bound Pokémon are required to reach level 30 or above.
4. Elite level: To activate the fourth bond slot, the first three Pokémon must reach level 50 or above, and at least one must evolve into its final form.
5. Master Realm: To activate the fifth bond slot, the first four Pokémon must reach level 70 or above, and at least 2 must evolve into their final form.
6. Legendary Realm: To activate the sixth bond slot, the first five Pokémon must reach level 90 or above and all evolve into their final form. At this stage, humans and the 6 Pokémon form a perfect soul resonance. Their own energy and the energy of Pokémon can be transformed into each other, and their strength is comparable to that of high-level Pokémon. When breaking through, there is a 10% chance of obtaining the exclusive skill of the bound Pokémon (such as Pikachu's Volt attack, Charizard's explosive burning). There are no more than 100 experts in the Blue Star Legend realm, and only a few people can collect all 6 skills to become "all-skill legendaries".
