How about Shikamaru in Naruto?

Shikamaru always looked lackluster and listless. He would rather lie on the roof and watch the clouds than take part in sports. His only hobby is to play shogi or go like some old men. He even slept with Kabuto's phantom suit unbuttoned to avoid getting involved in the fight, which was a nuisance for him. Sakura only discovered this when she solved his genjutsu. Another example is before he fought Temari, he wanted to give up the fight but was pushed into the arena by Naruto Uzumaki. When he is caught in an emergency situation and must concentrate all his efforts, he will always complain, "It's really troublesome!" The person who knows him best is himself. For this reason, he calls himself "the No. 1 escapee." However, when it comes to missions, Shikamaru has a strong sense of responsibility for his teammates. Even if he said he lacked courage, he would not hesitate to sacrifice himself for his friends, just like when he stayed behind to hold off the nine sound ninjas, giving Naruto and the others enough time to catch up with Uchiha Sasuke. Ever since he was promoted to chuunin, he had taken the lives of his friends even more seriously. Shikamaru is a genius strategist. Although his teacher Sarutobi Asuma often plays Go and Shogi with him, Asuma has never defeated him, making Asuma doubt that this man has super talents in chess games. Are the people from Hua and the guy with similar grades to Naruto the same person? Asuma gave Shikamaru an intelligence test (pretended to be a game), and the result shocked Asuma - Shikamaru was a genius with an IQ of over 200! Shikamaru himself respected Asuma the most. But the S-class mission he, Asuma, Izumo, and Kotetsu took on was mainly to kill Akatsuki's duo, Hidan and Kakuzu. But when fighting these two, Asuma unfortunately fell victim to Hidan's spell. It was this accident that made Shikamaru start to face everything seriously, and his personality changed 180 degrees.
