From the Start, I Was of the Hyuga Main Family. I Really Wasn't Flirting with Them!

The protagonist, Hyuga Xuanchen, is a member of the Hyuga main family. He is also one of countless people who have transmigrated into another world, having been reborn as a baby. His golden finger is a mysterious, unknown space. From the start, Tsunade entrusts him with taking care of Kushina. His outstanding talent, along with rewards from the mysterious space, gradually makes Xuanchen invincible in the Shinobi World. With the Byakugan's 360-degree, all-around long-range vision, how could he not make the most of fighting at a distance? He keeps earning rewards, purifying his bloodline and awakening the Tenseigan. He awakens Magnet Release, raising a sky full of yellow sand with a wave of his hand and killing opponents from afar with electromagnetic cannons. The Rinnegan is strong? Take this Golden Wheel Reincarnation Explosion! You survived that? Here's another one! But being too exceptional comes with its own troubles, like: “Hmph, I don't care. If you flirt with someone, you have to take responsibility.” “I don't care who flirted with whom!” “I'm telling you, I won't marry anyone but you.” Kushina “Um, Xuanchen, thank you for saving me back then.” “I think I've fallen for you. Could we take our time and get to know each other?” Mikoto “You jerk, going around flirting with every girl you see! I'm your fiancée and childhood friend, so don't you dare say you don't want me!” Hyuga Yunli There are currently three heroines: the Hyuga childhood friend who grew up with him, Uzumaki Kushina, and Uchiha Mikoto. (There probably won't be any more!) The protagonist is usually gentle, though he can be decisive and ruthless when needed. He keeps a low profile, quietly growing stronger. He'll learn the Gentle Fist, but he won't stop there. I've tried to address some common dislikes, such as transmigrating into someone else's body and power levels rising too quickly. If it's not for you, feel free to move on. Also, some events don't follow the original timeline exactly, so please don't nitpick and spoil your enjoyment.
