*A book falls from the sky in front of you and your fellow MotK'ers*
"Things have gotten boring lately. So I decided to let a little 'outside influence' slip in." a voice says from the darkness. "The book will give you the ability to have a little fun. I call it the 'Book of Gensokyian Minors'."

The first page is listed 'Rules':
To begin with; you must select a character to control.
You may only vote for one character.
The character cannot either be a major power within Gensokyo; or be strong enough to be one if they simply bothered. This excludes:
Yukari Yakumo; Ran Yakumo; Remilia Scarlet; Flandre Scarlet; Reimu Hakurei; Marisa Kirisame; Sanae Kochiya; Suwako Moriya; Kanako Yasaka; Utsuho Reijui; Eirin Yagokoro; Kaguya Houraisan; Lord Tenma; Byakuren Hijiri; Toyosatomimi no Miko; Mima; Yuuka Kazami; Shinki; Tenshi Hinanawi; Shiki Eiki [Yamaxanadu]; Mamizou Futatsuiwa; Suika Ibuki; Yuugi Hoshiguma and ANYONE who currently resides on the Moon or in the Real World.
The character you vote for must have a name
It is possible for multiple characters to be under command. Some situations involve characters who are inseparable; such as Unzan and Ichirin. Others may be a case of subordinates; such as Seiga and Yoshika. Others may arise as you play. Other situations exist where control may be granted over multiple characters. It is important to note even characters who are a group; such as The Three Fairies, will not have control granted over all three if you pick one. To have control over a character you must gain it.
Every character has different attributes, abilities and items. They are better and worse at tasks than others. An example:
Keine, in her human form, would have among the lowest strengths in the game, unable to hit as hard or lift as much. She is not very fast or agile; especially by Gensokyo standards. However, she would be able to perform things that require a lot more brainpower due to her intellect. Flying would be more tireing for her than most, since it is not a natural human thing, nor her ability [Like Reimu].
Compare Cirno, who is pretty fast and agile [aided by her size] but attempting to do anything that requires a decent amount of actual brainpower will probobly fail. Cirno is also even weaker physically than Human Keine. Flying is virtually effortless for a Fairy.
You may ask for a summary of key points of a character during the selection process.
Note it is possible for actions you command characters to take to fail based on a lot of factors. Do not expect Cirno to be able to talk down a situation well. Do not expect the anti-social Alice to be particularly good in social situations. Do not expect Aya to happily go underground and talk to Yuugi due to the history between Tengu and Oni. Your 'commands' act as the character's thoughts. Not their actual ability or actions. Of course, you can overcome these weaknesses, but it would take practice and effort on the character's part.
