Mahouka Koukou no Rettousei: The irregular has weird magic

He died in his previous world after miserably failing at the creation of a new spell, he thought it was the end, but somehow he got reincarnated in this world where there are magic academies and people use a weird type of lowkey magic that relies on casting tools. With his knowledge and talents, Shiryu will live a high-profile life in this world, showing off whenever he cans and to whoever wishes to see, because fame and recognition is never too little.
