"Congratulations, host, for gaining Sakura Haruno's intense attention. Reward: S-rank ninjutsu [xxx]!"

"Congratulations, host, for gaining Hinata Hyuga's secret affections! Reward: S-rank ninjutsu [xxx]!"

Naruto Uzumaki stared blankly at the system notification that popped up in front of him. He just wanted to become Hokage, so why did he have to rely on collecting girls' affections to become stronger?!

What gave him even more a headache was that the list of "targets" provided by the system was ridiculously long—ranging from his classmates to Kage-level powerhouses from rival villages, and even including a few individuals with special identities...

Many years later, when the Fifth Hokage reviewed the battle records, he was surprised to find that the student who called himself a "straight man" had unintentionally facilitated the strongest peace alliance in the history of the ninja world.

I'm from Fairy Tail, skilled in accepting magic, but my accepting magic is a bit off. Let me tell you a secret: I'm actually... a transmigrator. 【Multi-dimensional, All-encompassing Acceptance】 This is my accepting magic, capable of accepting beings from another world. All-encompassing acceptance means accepting all of their abilities. Understanding, analyzing, accepting... the moment you genuinely acknowledge and strive for the object of your acceptance, the door to evolution will open for you. Becoming the strongest mage requires three steps: summoning, accepting, evolving, and then becoming the strongest. "So, do you think I'm human, dragon, beast... or god?" "None of those, I am who I am!" "The strongest mage in Fairy Tail." One punch shatters magical dreams, one kick sends black dragon souls flying. Enough talk, take this punch!
