(A Crossover) You've Been Summoned

The gods declared: Awaken, chosen boys! And so some people transmigrated, some were reborn, and a few others... turned into perverts. --Who are you? --I am Yoshida Shoyo. --I thought I'd transmigrated into a historical setting. Hey, hey, wasn't he supposed to be Yoshida Shoin? What's with Shoyo? Is this some cursed-twins legend? --I taught you to hold a sword, not to use it to hurt others, nor to hurt yourself. --The ways of the world are as vast as three thousand streams. Which will you choose? --Though these eyes of mine can see far, I don't want to concern myself with distant matters. There's only so much kindness in this life. Being able to protect the people you love most is already more than enough. #Gintama AU# A story about Master Shoyo being reborn into Katekyo Hitman Reborn, taking on his first students and lowering the whole world's standards of decency. The main characters are Shoyo's disciples. #Dual protagonists#? The Vongola crew will have to wait a little longer for their turn. When the chosen boys follow a summons to another world (mist) When Shoyo's disciples start taking great delight in messing with the Vongola (thick mist!) When the first-generation Vongola spontaneously form a team to grind through anti-shogunate patriots (blinding fog!) When a dead-fish-eyed sweets lover and a 170-centimeter-tall sadistic bastard gaze into each other's eyes, fall instantly in love, get into all kinds of trouble together, and stay true to each other through life and death (divine fog!) BGM: Qiuxiang (Two Heroes), instrumental Inspired by the lyrics: Two birds fly freely through vast skies; one cup of wine, and each heads to a far corner of the world. Though friends may part at the ends of the earth, their bond remains. When they meet again, they'll drink and celebrate; if you'd take a knife for me, I'd bare my heart to you.
