It's been three years since issei has made to the shrine to Truck-sama, he prayed to it everyday as to thank Truck-sama for this glorious opportunity. As he turned four, he thought of ways to gain strength, he could not do any excess training so he did some yoga to retain his flexability, and completed saitama's training manual without the runing as he could not leave his house to far.
Though the one thing he could train in, magic was the worst. Don't get him wrong he loves magic and it's possibilities, but... math. He had to learn fucking math. He is still not a supernatural like a devil, angel or a fallen, so insted of his imagination, he has to think of equations.
For the simple magic like increasing cell division to increase his natrual healing, it is not so hard, if you would convert that to an equation it would be like 1x2=2x10=20/2=10, to increase his healing speed to 10x a normal person, but for teleportation not only do you need to think of the equation to cast it(I still can't get the equation right) you also need to think of coordinates and Latitude&longitude, magicians that could cast teleportaion magic are monsters in my opinion.

Issei Just turnt 7 last month. He had after much time, with patience (and several tantrums)*ahem* anyway he finally managed to convince his parents to get an ear pricings in his left ear on his 12th birthday. Why would issei want earrings you ask simple. Enchantment .
After three years of practcing magic he ran into a problem, he could cast [Regeneration], his self healing spell passively but he can't cast any other spell in the mean time. at the start it was not that bad because he did not need to cast any other spell, but as he got older he started to do more strength training untop of his yoga, but the results of his training were decreasing. So he started to research gravity magic, to incrase his own gravity by small amounts to incrase his strength and speed.
When he found out he couldn't cast multipal spells at the same time(because his an idiot, other magicans can do why can't you), he looked to enchantment's, all he had to do was write the equation onto the earring create a magic condutor on the earing, create a personal symbol for the conductor, supply mana and it works.
Issei has made three spells on his own [Regeneration],[Body Strengthening],[Increase]. His regen spell can heal wonds at accelerated speeds, though it still can't regrow body parts. strengthing magic is basic as it strengthens his body as a whole, musles, bones, organs, skin, hair everything, and yes most importantly his dick and stamina. Increase is just incraesing the gravity on his body, with a dial.
