I am Nohara Sulan! 5 Years Old!

Shinnosuke Nohara: "I... am the coolest 5-year-old kindergartener in Kasukabe. I have a mischievous younger brother who often tricks me. You could say I'm only alive thanks to my protagonist's halo. But my brother is also very amazing. He always manages to come up with some really fun things. He also has a lot of cookies and takes me to buy lots of toys. Our adventures together are very interesting. I love my brother very much."
