Tokyo ESP by Hajime Segawa.
I gave this book ★ ★ ★ ★ ★ 5 stars, I loved it.
Rinka Urushiba is your average high school girl. She goes to class, works a part time job after school and helps her dad around the house, they are poor but happy. One day on her way home from school she sees a flying penguin and chases after him hoping to catch him and sell him to help her finances. Instead she is thrust into a completely different life than the one she led before. A strange boy shows up everywhere she goes trying to convince her to become a 'hero of justice' and that is the least strange thing in her new life!
Rinka is a sweet character who is easy to relate to with one heck of a strong kick. Azuma seems like a nice lighthearted kid with a big sense of adventure but the brightest smiles sometimes hide the most tragic pasts. Each new character that joins the cast has their own unique personality that adds to the depth of the story. Whether they are an ex-cop, a professional thief, a yakuza boss' daughter or a helpful barkeeper each character has something to add to the story.
I highly recommend this book. Really what is not to love about it? It's got a flying penguin, mysterious superpowers, great characters, an intriguing plot line and a few beautifully colored pages! You should definitely give this a chance if you enjoy sci-fi or mystery manga.
