Spell cards (スペル牌 Superu fuda) appear to play an important role in casting powerful character-specific magic in the Len'en Project. During a spell card trance, the user's offensive and defensive capabilities appear to increase greatly. In some cases, the user becomes completely invincible for the duration of the trance. However, the user may only cast the spell that was specified by the spell card until the trance ends, limiting its overall usefulness.
Making Spell Card
Making a spell card takes quite a certain amount of time that depending on its power, learning how to make a spell card takes practice, but a "natural" can make them by instinct. Once a card has been made, the maker can make indefinite copies of them. When a spell card is captured, i.e. taken from them, the owner cannot make copies of that spell card until it is returned.
Currently, the known "Naturals" are:
- Yabusame Houlen[a]
- Tsubakura Enraku
- Aoji Shitodo
- Hooaka Shitodo
- Kuroji Shitodo
- All of the Senri Shrine priests, Tsurubami Senri included
- All Homonculi: Para's body (Now occupied by Taira no Fumikado)
Game Spell Cards
In the Len'en Project games, spell cards manifest themselves in a few ways. In the shoot 'em ups, spell cards primarily act as a source of danmaku by enemy characters as they shoot a pattern or sequence of bullets at the player character, who tries to dodge them. They each have a name of some sort that's required, and the names notoriously use quotation marks (「example」). The spell cards contain health bars as usual that need to be emptied in order to defeat the spell card. These are usually used by bosses and midbosses on stages and have never been used by a stage enemy. As well, they are used as life-saving "bombs" by the player characters to become temporarily invincible and cancel out bullets.
Spell Card System
The first character to use the system on-screen was Kurohebi. The idea of the system is based on the spell card system from the Touhou Project . In the story of the Len'en Project, however, spell cards have been stated to have different origins than in Gensokyo . The exact details are unknown, but they were apparently invented by the Senri Shrine's yet-unnamed second generation priest.
Mugenri's spell card rules dictates that the winner of a spell card duel can order the loser to do anything, even killing themself. Disobeying this order would result in Mugenri erasing their existence. An order can, however, be withdrawn and one can avoid listening to the order by fleeing from the winner's sight before they issue an order. It is also possible to override existing spell orders with newer ones, although there is little chance of this actually happening in the series.
Unlike Touhou's spell card rule, Mugenri's spell card system was not designed to give people a fair fighting chance, so there is a risk of death, making Mugenri a dangerous place to live, according to the games' manuals.
