Joutenki refers to a clear, sunny sky. This seems like a slightly odd temperament for this Reimu since she doesn't have the sunniest disposition. Reimu acts as freely as the wind (Wood Phase), but she also has responsibilities as the Hakurei shrine maiden (Sun Essence). The strong and kind Wood Phase resists Water Phase, because water nourishes wood, but it is weak to Metal Phase, because metal carves wood. The alluring and arrogant Sun Essence resists the diverse and uncooperative Star Essence, but it is weak to the cooperative and indecisive Moon Essence.

The ability of Reimu Hakurei from Multiverse Trail 4 (a Touhou LW original). It's basically the same as the abilities belonging to most other Reimus. An altered path of fate cannot always be explained by simply following its branches back to the beginning. Seemingly inconsequential differences at the start cause gaps to form that eventually grow so big they devour everything. It's like how two ships setting sail side-by-side can end up miles apart when they reach the opposite shore. This behavior is known as chaos. But chaos isn't anything special. It exists in all things. Reimu Hakurei's life was meant to be much more peaceful. Well, perhaps "peaceful" isn't the correct word. Even compared to previous Hakurei shrine maidens, she's usually quite busy with resolving incidents and exterminating youkai. Despite wanting nothing more than to laze about drinking tea, she always seems to get caught up in something. This applies to most Reimus, including the big blue Reimu. However, this tiny Reimu takes this to the extreme. Why is she in such a rush? This parallel world shouldn't exist. It was conjectured and then subsequently judged to be impossible, like a rough sketch shut away in a drawer with the others, never to see the light of day. It is by removing impossible fragments like this one that the remaining fragments can shine. The following is a fortuitous report written by a lunar princess who acts as a vessel for divine spirits. It was recorded in her old-fashioned notebook. "You shouldn't beat yourself up about it, Reimu." After enduring Yukari Yakumo's harsh tutelage, Reimu was sent to the Moon to complete her training. There, she met a Lunarian lady―a mythical god-summoning expert. She was also an experienced shrine maiden. "Y-You think?" "I don't fully understand what you're going through, but you and I both have the power to summon the Yaoyorozu no Kami." The lunar princess gracefully drew her sword and then stared at its blade. Reimu was told that even though that sword doesn't have the ability to summon gods, as one of the three sacred treasures, it can act as a vessel for divine spirits just like the princess. It's strange, but perhaps that's why she saw a crescent Moon when she looked at the sword. "Be it in training or battle, I have called down all kinds of divine spirits to inhabit my body. Do you understand what that means, Reimu?" Reimu tilted her head to the side and considered the question. The lunar princess usually trains rabbits, and Reimu was pretty sure that rabbits couldn't summon gods. That would mean that training her to summon gods was a rare opportunity for both her and the lunar princess. That was all the tiny Reimu was able to figure out. "No, I don't..." "Haha, I expected as much." A forest of peach trees lined the Sea of Tranquility's shore. However, they weren't normal peach trees but lunar peach trees. Their leaves never wilt, and they bear fruit all year round. The otherworldly peaches that hang from their branches constantly exude a sweet and fantastical scent. Reimu sat down on a big root, exhausted from all the training. The lunar princess handed her a peach and gently patted her head as if saying she could eat it whenever she wanted. Reimu found it hard to believe that she was the same princess who fought her so fiercely in a battle of bullets earlier. "As you summon more and more gods, you begin to lose track of who you are. You lose only a tiny sliver of your identity with each summon... but it builds up over time." "What?" Reimu dropped her peach as she saw a shadow cast over the princess's face, like a waning Moon. "That's why it might be a good thing that you think you're not ready to summon gods yet. The fewer gods you summon, the better." [The report ends here.] Mini-Tajikarao (Early Form) Due to this Reimu's altered fate, her friend became a Satellite much earlier than planned. Mini-Tajikarao is a special type of Satellite called a Foundling. In this tiny form, it is almost impossible to read what she is thinking unless you're a satori youkai. That said, she doesn't seem to have any issue with how things turned out. In fact, she seems to enjoy hanging around the tiny Reimu. Perhaps she feels obligated to express the emotions that Reimu keeps bottled up inside.
