Detective Conan: As Venom, My Host Is Ai Haibara

[No transmigration + no System + one female lead + not invincible + Marvel + parallel universe] (Not invincible + no System + no transmigration + not a wish-fulfillment story. So Venom may seem rather pathetic here. Some readers who find that stupid won't want to continue, so I'll be upfront: Venom's [higher-dimensional lattice] has been damaged, and many of his abilities are currently unusable.) As for whether Venom can turn into a human? Of course he can!! There may be plot developments you’ll enjoy later, but be sure to read the setting carefully!
