In the game ‘School Magical Simulator’, there are many ways to eliminate your first rival David, a tsundere that has been childhood friends and classmates with Joshua for a long time. He acts very harsh and mean, but he has a huge crush on your beloved chosen senpai crush, Joshua. Soon enough, David will eventually confess his feelings to Joshua, causing Joshua to accept and for them to be together. Because of this, you must stop David at all costs and eliminate him for good.
The fan vent elimination will be explained on how to do. This choice allows the player (you) to trick David into going up on the school rooftop, where you await with a screwdriver found from the storage room, and opening the fan vent, you grab David by the hair and pull him inside of the fan vent, ending in his successful elimination and ending up killing him. However, you have to get rid of the lifeless corpse, by carrying him and putting him in the incinerator, causing his deceased body to burn away, or sneak into the gardening club and burying him with a shovel in one place, or any other method you choose. Then you must clean up and hide away everything that will cause other students, teachers, or anybody that will be shocked to discovery of the corpse and call the police, tell others, or inform a staff member.
You then change and wash up yourself and wear new clean uniform in the boys/girls showerbath room. Doing that on Wednesday will benefit, as David tells your crush by that day to meet him at the school rooftop at lunchtime, (12:00) as David secretly cooked himself and Joshua a lunch to eat together by a bench nearby the other sitting areas. You can only eliminate David by the fan vent much earlier before class time and lunchtime. He will not get the lunches, and Joshua will give up on waiting for David to come. You go and chat with senpai while eating your lunch with him. The next day, David will be looked for, and be reported as missing or dead.
