Shiro

Shiro (シロ) is a supporting character in the Heavenly Delusion series.

Appearance

Profile
Shiro is one of the children living in a world inside the walls. He is good at mechanical engineering and has a liking for Mimihime. While he is quite shy and socially awkward he is well respected by his fellow students.

He is easily embarrassed as merely the sight of two people kissing is enough to give him a nose bleed and cause him to pass out.

Takahara Academy
Shiro as a young boy was awkward and not very sociable with the other students of Takahara. He's always had a crush on Mimihime, often staring at her through a higher floor; something that Mina noticed. One day Shiro receives a photo through his inbox on the school tablet, with the sender as Mimihime. He opens the photo and is left in shock to find it as a picture of Mimihime completely nude, taking a shower. This causes him to later approach her and ask her about it. However, Mimihime is puzzled, as she had never sent him anything the previous night. Shiro goes shy about it, so she presses him. He lets his feelings out for her, though she doesn't really understand.

Extradition
With Japan now aware of Takahara's Heaven and their involvement with the dooming of the entire world, they retaliate with a bombing and breach the facility. Curious, Anzu, Taka, Shiro, and Mimihime venture out to the real world, and are left stunned by the uncomfortable terrain and temperature. The four of them agree to split, thinking of the circumstances as a test.

They continue to walk and walk, until they find that they're lost now. Mimihime notes that Shiro talks much more when they're alone than he does with anyone else. Embarrassed, he stops. Using her specialized ears, Mimihime can make the sound of running water in the distance. After a few minutes of trudging through the woods, they spot the stream. Mimihime, excited, doesn't check her surroundings and steps on an unsupported ledge, causing her to fall. Shiro dives after her and takes the brunt of the force. Baffled, she asks why he would risk his life for her, he responds by confessing his feelings. After hearing him, Mimihime takes one of her Takahara pins off of her uniform and gives it to him.

Later, Aoshima finds the the pair on a road and uses this chance to take the four kids with the intent of completely extraditing them from the facility. They are then integrated into society, learning all kinds of new things.

The Immortal Order
15 years later, Dr. Usami meets Maru and Kiruko in the garage of his building. Having just witnessed Maru kill the Hiruko dwelling within the area, he asks him to do the same for a person. They agree and move up to the higher floors of the building. Maru and Kiruko remove the curtain and are left horrified to see the breathing corpse of Mimihime. Usami requests that he finally end her life, so that she does not morph into a full Hiruko. Maru agrees; though requests that she give her consent. Mimihime asks to see the sky one last time, and so they wheel her out to the balcony. She smiles and Maru crushes her core. She leaves one final message for Shiro, and he bursts into tears.

Later that night, Shiro finds himself atop a building, escorted by Maru and Kiruko. He fiddles with the pin Mimihime gave him, puts the gun he had been holding to his head, and pulls the trigger.
