I... sort of want to add the Master Spark to Touhou's abilities. It's one of the most iconic attacks of one of the two main characters. It's essentially a large laser (
fueled by love), somewhat similar to the Kamehameha. It would be quite limited in usage, only usable once in a while (partially because it's a Bomb in the games; very strong attacks that you can only use twice per life barring other pickups, and partially because of how strong it would be otherwise), and is channeled through something called the Mini-Hakkero (essentially an octagonal amulet with a hole in the middle).
