What If Cullom Traveled to a Superhero World [Comprehensive British and American]

Vongola has two mist guardians, Sui and Cullom. Sui has a weird and perverse personality, while Cullom is well-behaved and docile. Although Mr. Tsuna gave Tsuna a headache, the presence of Chrom made up for it. Cullom will complete tasks on time, will write reports honestly, will never fight randomly, will take the initiative to become a middleman for communication and mediation, and will gently say "Thank you for your hard work, BOSS". Simply angelic. Tsuna was always glad that there was Chrom in this world. Until one day, his subordinates rushed into the office in panic. "Judaime, it's bad! Master Cullom was hit by a rocket launcher from ten years later and went to another world. Master Kashiwa was furious and wanted to dismantle the technical department and Master Rambo——!" Tsunayoshi: "..." The effect of the rocket launcher ten years in the future is that the person hit exchanges with himself ten years in the future for five minutes. Cullom waited in another world for countless five minutes with no change, and finally realized something was wrong. The shadow of the bat flashed across the sky above the water droplet, and the news headlines about the battle between golden and red armors and robbers popped up on the phone. She felt the extremely weak soul contract between her and Mukuro, and felt uncontrollable fear. "Hey, you don't look good." Robin crouched on the patio above her. "Where is this?" Cullom asked. "Gotham." Robin said, "Do you need an introduction to homeless housing? The Wayne Group sponsors it." Later. Chaoying has a powerful illusionist companion. Cullom is good at everything, but there is always one person in his mouth - Liu Dao Gu. "Who is Mr. Bones?" Cullom said with a smile, "He is the most important person in my life." Intention: Loving others is also a process of pursuing oneself.
