Summoning Across Boundless Realms

"Like every night, Yue Qianyu fell asleep while watching his favorite anime. However, a loud noise woke him up.
"Where am I...?"
As he observed the confusing events around him, a cold and robotic voice sounded in his head.
[Ding! The Infinite Dimension Summoning System has been activated!]
He, who was about to be hit for unknown reasons, had transmigrated to another world. But not just any world, but that of his favorite anime.
[Host: Yue Qianyu]
[Current world: Fire Shadow Ninja]
[Level: Waste]
[Ninjutsu Techniques: None]
[Available worlds: None]
[The system has been successfully activated.]
In a world where skill and strength are everything, Yue Qianyu gained a tremendous advantage.
Not only could he level up, improve his skills, and learn incredible ninjutsu just by completing system missions, but he had also obtained the summoning ability, one of the most incredible in the ninja world. 
But instead of creatures, he could summon any anime character he wanted.
"When I reached the level of a Super Shadow, I would summon Kakarot and use a single Vital Energy Bullet to destroy all of you!"
