As My Sister's Strong Support, I Can Only Be Invincible

[System analysis + time travel and rebirth + invincibility + endless love for girls + daily life + travel style + level differentiation + slow pace + group image shaping and growth] Note: I would like to show my affection to the heroine Serena, but not Zhina. The protagonist has no cp. Yuri, a loyal Pokémon fan on Blue Star in his previous life, died and was reborn in the Kalos region. He also had an identity that confused him—— The biological brother of Serena, the heroine of the Pokémon anime. Looking at the cute little sister in front of him who has been calling him brother since she was a child, Yuri swore on the spot: In this life, no one wants to let my sister suffer any injustice! My sister wants to be a Pokémon performer? ——Brother will take you to capture the most beautiful and rare Pokémon! My sister is going on a trip? ——Brother will accompany you! Whoever dares to bully you must get through me first! Later, Yuri, who is the champion of the Carlos region, looked at his sister who had become the world's number one performer, and his eyes were filled with joy. The world view is mainly biased toward anime TV, with some special episodes and memorial settings for the king. This book is also called: "Elf: The Legend of Carlos's Sister Control" and "Elf: Above the Crown"
