Bamboo Horse VS 1000% College Love Dropped from the Sky, the Undecidable Wink in the Ultimate Shura Field

I wrote this book to record my first encounter with two friends. Use a diary-like format. I don't know what else to write next. By the way, it seems I haven't introduced my name yet. My name is Ishii Si. Please have no doubt that the surnames and first names below are all true. But it seems because the world is different. So you may not be able to find this surname, but that's not important. It seems like the length of the introduction is enough. So that's it. Intention: When we meet, we sign up.
